NOTE: It should be noted that readings obtained with different set analyzers will vary with battery voltage and with different tubes. The readings shown, therefore, are only average readings. For this reason, each service man should compile a chart similar to the one illustrated, using his own set analyzer with a set, and batteries that are known to be operating properly.

DEWALD RADIO MODEL 61 Socket layout Alignment
RECEIVER To align the I.F. circuit, an oscillator sup - ALIGNMENT plying 456 K.C. should be connected to the
control grid of the 6A7 and the variable con- denser frame. The grid cap normally on the 6A7 should be removed. The oscillator section of the variable condenser should be short circuited. This may be done by putting a small clip on the terminal of the oscillator condenser trimmer and running a wire to ground. It is preferable to use an output meter for accurate work, which may be connected into circuit of the 41 by means of an adapter having leads brought out from plate and screen through a .5 mfd stopping condenser. See Fig. ih4.
The volume control on the receiver should be turned to maximum and the three I.F. adjusting screws shown in Fig. #2 set to give maximum on the output meter. This operation may be performed with the receiver in the can if a pair of long nose pliers or offset screw driver is used,
For R.F. alignment, remove oscillator condenser short circuit, replace grid cap on 6A7 and connect oscillator covering broadcast range to antenna wire and its shield.

MODEL 61 Notes
DEWALD RADIO
Be sure shield of battery cable is soldered to can at left side of receiver,
When cover is placed on can, a heavy spring on the inside grounds the top of ''B" supply unit. Be sure contacts is good and pressure heavy.
Condenser from antenna transformer should run to front of variable condenser. If further difficulty is ex- perienced check ground of chassis and "B" supply unit to can at various points with heavy screw driver.
The wire on vibrator which runs from its coil to the frame, should be securely soldered on frame and on inside of vibrator case.
POSSIBLE A, Low volume or weak signals SET TROUBLES 1. Defective tubes.
2. Poor antenna (small size shielded wire must not be used to extend present antenna, as capacity between shield and inside is too great.
3. Open circuit in radio frequency or audio stage.
4. Defective resistors. 5. Defective by pass condensers. 6, Defective volume control 7. Low . "B'; voltage.
B. Intermittent reception. 1. Antenna shorting (usehigh resistance continuity
to check car antenna -set disconnected) 2. Defective tubes. 3. Loose connection. 4. Film breaking down in electrolytic condenser 5. Defective speaker 6, Defective volume control 7. Defective by pass condenser

DEWALD RADIO MODEL 61 Vibrator data
VIBRATOR To examine vibrator, remove "B" supply unit ADJUSTMENT from can by unsoldering 3 leads
(see Fig.3) removing 6 screws at ends of unit Take cover off vibrator case and vibrator may be removed without unsoldering its lead? wires. It will be seen that there are a top and a bottom set of contacts. The normal clearance on these contacts is .003" to .004" and this may be adjusted with screws provided.
Any dirt on contacts should be removed with pipe cleaner before adjustment. If top clearance is too great vibrator may operate but not close this circuit (operate half wave) and the voltage will be low. If bottom clearance is too great, vibrator will pull down but not vibrate. Tao small a bottom clearance may short bottom contacts and cause in. operative vibrator and heavy current drain.
If both contact clearances are small, the vip brator will operate at a higher pitch and voltage, but spark- ing will occur.
Check of vibrator operation may be made by running three temporary jumpers from "B" supply unit outside can to the receiver, (See Fig.3) and operating the vibrator outside its case so it is visible. The tone should be low pitched, even and regular, and no appreciable sparking should occur. To remove vibrator for replacement purposes, unsolder the three vibrator wires at the terminals of the step up transformer and at the ground terminal near the tube. Leads should be left attached to vibrator.
If set is not available or is in doubtful con dition a 4000 ohm load resistance of 5 watts or larger may be used from plus ''B" to ground of eliminator in place of set, The 6 -volt supply is applied to the two terminals at the vibrator end of "B" unit.
If gaps are okay, and sparking persists, check for dirty contacts or open condenser across primary of step»up transformer, Vibrator Base is Grounded

MODEL "Light-O-Matio" THOMAS A. EDISON, INC. Cable drive data
1. DRIVE MECHANISM. Twenty pound test line is specified and used for driving the dial mechanism. Each end of the belt is secured to the large pulley wheel. The ends pass through holes on opposite sides of this pulley and are held by knots tied in the belt itself. The belt pasees over two smaller pulleys in a spring -actuated take-up assembly, thence to a worm rnhich slips over the tuning knob shaft.- Five turns are made by the belt around this worm. The worm is not directly secured to the tuning knob shaft but is held in position between two collars locked to the shaft. A spring washer is inserted between the worm and the front collar. The spring washer being adjusted so as to provide friction to a sufficient degree, exceeding the driving resistance of the dial mechanism itself and its associated condensers; yet insufficient friction to resist continued rotation of the tuning knob when the dial mechanism has been rotated to either extreme end, thus preventing slippage or breakage of the belt after proper adjustment has once been made.
2. SPRING -WASHER. Receiver units bearing serial numbers ranging above 725000 have been equipped with a spring washer of improved design, greatly diminishing the possibility of dial slippage. The improved washer may be distinguished from the earlier style washer by its cup -shaped appearance, much of which it retains even when adjusted to ff position for maximum friction.
3. DIAL SLIPS OR STICKS. Sticking or slipping of the dial may result if the spring washer is not adjusted for sufficient friction against the drive worm or if the belt is
too loose.
4. ADJUSTMENT OF SPRING WASHER FOR INCREASED FRICTION. Note Figure 12. Observe the r-elr.tive positions of front collar, spring washer, drive worm, rear collar and bearing plate "B".
NOTE: IP dial slips and continues to
slip after collar has been for-
ced forward for maximum frict- ion of spring washer against worn, then inspect "take-up
assembly. If distance "x" is
less than 1 -16th inch, belt
should be tightened in accord- ance with instructions.

MODEL "Light -O -Matie" Cable drive data THOMAS A. EDISON, INC.
Rotate dial to approximate position as shown in Figure No. 12 so
that these parts are most readily accessible with long blade
screw driver. Loosen both set screws in rear collar. Insert
screw driver blade between rear collar and bearing bracket,
indicated by "Z". Force the rear collar forward, in the direction
of the tuning knob, by twisting the blade or prying against the
bearing bracket. This action compresses the spring washer
between the worm and front collar, providing greater friction. Then, with a narrow blade screw driver, tighten set screws in
rear collar, making sure that rear collar does not shift before
the second set screw is tightened. This operation properly performed will eliminate slippage of the worm.
5. OIL should not be applied to the spring washer or worm. The application or presence of oil on these parts promotes slipping and will defeat proper functioning.
6. TO TIGHTEN BELT. Although not absolutely necessary greater accessibility may be had by removal of the front panel.
Then remove the right hand variable condenser shield. Loosen the two set screws in dial mechanism that hold the shaft of the right hand variable condenser, and then push the rotor plate assemblies into position of maximum capacity so that the possibility of damage to them is reduced to a. minimum. Consult Figure No. 13. Rotate the tuning knob until the large pulley with the knot "K" is in the approximate relative position short in Figure No. 13. Insert screw driver blade as shown between chassis shelf and take-up assembly bracket. Lift upward on this screw driver, compressing take-up assembly spring "S", and loosening belt "i
, Block screw driver blade as illustrated at point "X", thus maintaining looseness of belt. Then pull knot "K", taking up slack in belt:"?".: Then tie a new knot in this belt as near as possible to the pulley face. It is
usually advisable, if possible, to untie the original knot to avoid its rubbing against the condenser shield.. When the new knot has been formed, remove the screw driver, rotate the tuning knob in a counter clockwise direction (to the left), turning it
as far as possible. Then tighten the set screws that hold the dial mechanism to the shaft of the right hand variable condenser. Replace the right hand condenser shield, front panel and knobs.
7. NOTE. It is always advisable, after removal or replacement of panel or when any adjustment of the variable condensers is made, to reneutralize and then recompensate to insure most accurate calibration. These operations are explained in detail in bulletins numbered 3 and 4.

MODEL 072-A Installation notes
ELECTRIC AUTO LITE CO.
The chassis is received with the condenser pulley, spring and centering ring mounted in the proper position on the tuning condensar and the cable chuck through which the drive cable passes mounted on the chassis box.
All that it is necessary tó do is to mount the control unit on the steering column, cut the cable and housing to length if necessary, attach the cable to the
drive pulley, and secure the housing in the chuck.
MOUNTING THE CONTROL UNIT
The control unit is mounted on the steering column with the knobs extending to-
ward the right hand side. The proper distance below the steering wheel can be
determined by trial.
Two clamps are provided to secure the control unit to the steering column. Use
the lockwashers supplied under the heads of the clamp screws to secure the clamps
on the control unit.
If the steering column is l` in diameter, use the leather spacers supplied. If
1-5/8", split the spacers or wrap the column with about 1/16" of friction tape
under the brackets. If the column is l-3/4", no spacers are required.
ATTACHING THE CABLE
The drive cable should be tun in as straight a line as possible. Avoid any sharp
bends.
After the control unit has been mounted and before securing the drive cable and
housing at the chassis, cut it to length if necessary. Be sure that enough cable
is allowed to avoid any sharp bends. Do not coil the excess length in short loops.
To cut the cable proceed as follows: With a sharp three -corner file, file across
one of the turna of the tubular housing until it is practically severed. Then
bend it only slightly back and forth until it breaks off. Do not bend sharply
as in so doing permanent injury to the inner element of the cable might result.
Turn the station selector knob on the control unit as far as it will go in a
counter -clockwise direction. The cable will then extend out of the housing the
greatest distance.
Loosen the large jam nut on the cable chunk. Insert the free end of the cable
and its tubular housing. Be sure that the housing with its weatherproof cover-
ing is inside the chuck. Then tighten the jam nut. This will secure the hous-
ing and weatherproof braid in place. As explained above, the station selector
knob should be turned to the extreme counter -clockwise position. The rotor of
the tuning condenser ig held at the extreme clockwise position by the action of
the spring. Bring the free end of the cable around the pulley, loosen the cable
clamp screw at the top of the pulley, insert the cable under the clamp washer
and than tighten in place. Cut off any excess cable to prevent tangling with
other parts of the receiver. Care should be taken not to put a sharp bend in
the exposed portion of the drive cable, as the latter may be permanently injured.
After the cable head is in place on the chassis. and after the drive cable is at-
tached to the pulley, chock the centering of the cable, chuck with the pulley. If
necessary to re -center, loosen the nut which secures the chuck to the chassis box.
Then move the chuck until the cable is centered relative to the groove in the
pulley and re -tighten the nut.
PIAL LAMP
The dial lamp may be replaced by removing the station selector knob and the two
screws on the sides of the control housing, Use a standard 6-8 V. screw base lamp
which may be procured from the factory. As a temporary measure, a 6 volt pilot
light bulb may be procured from any radio store.

nstallation Notes
INSTALLATION PROCEDURE
(Follow closely for easy installation)
1. Open carton, unpack set and check equipment furnished.
2. Remove the two thumb -screws holding the mounting plate to the radio cabinet proper. Tip the
mounting plate back and unhook it.
3. Remove the top cover and check visually conditions in general, i.e., tubes, grid caps, remote tun-
ing drive, etc.
4. Using the mounting plate (Figure I) for exploring, determine the most satisfactory position for
mounting in the car. As the mounting plate has the same area as the frontal area of the radio cabinet, any
space which will accommodate the mounting plate will be satisfactory, (allowing clearance for the set
to tilt forward for inspection after being installed).
5. Using the mounting plate as a template, locate the holes for the three mounting bolts. Check
under engine hood to see if bolts will be clear. Optional mountings may utilize 2, 3, 4 or 5 mounting bolts.
6. Drill these three holes. Suggest using IA" drill as a pilot hole then finish with % drill.) Put one
lock washer on each 5/16" bolt and insert thru the plate. Put a nut on each bolt and fasten securely against plate. Put a spacer nut and lock -washer on each bolt and mount the plate on auto bulk -head. Allow %" to 1" clearance between back of mounting plate and bulk -head for ventilation and good tone quality. Now tighten the bolts from the engine side of the bulk -head using a lock -washer and nut for
each bolt.
7. Before proceeding further, at this time, check the polarity of the car battery; that is, determine which side of the battery is grounded. This may be done most conveniently with a low reading D.C.
volt -meter. However, experienced mechanics may recognize the positive terminal of the battery by the fact that it is usually larger and blacker than the negative terminal. If there is any corrosion present, GREEN corrosion will be round at the POSITIVE terminal. Do not take chances or guess at the polarity but use every means to determine it correctly, as the wrong connections may cause serious damage to the receiver and car battery!
8. If the POSITIVE terminal of the battery is grounded, no changes are necessary and the instal- lation may proceed.
If the NEGATIVE terminal of the battery is GROUNDED, it is required to make a slight change in the receiver. This is done quite conveniently by removing the top strew and loosening the bottom screw holding the serial number plate to the right side of the receiver cabinet. Tip the plate down and reverse the red and black -marked spade lugs. When this is done, the black -marked lug will be on top and the red -marked lug will be the lower one. (See Figure II and red tag on battery cable.)

9. Replace the top cover on the receiver cabinet, using the screws to fasten it and attach the radio cabinet to the mounting plate; first, by hooking the two hooks on rear of the cabinet into the slots of the mounting plate; second, by inserting the two th umb-screws into the holes on the top of the mounting plate and screwing them into the holes of the cabinet. This completes the mounting of the radio cabinet.
10. Attach Remote -Control Unit to a convenient position on the steering wheel column, allowing the cables to take a smooth path to the set. Leather strips are furnished to accommodate unusual size steering wheel columns and also to prevent marring finish. Screw down the set screws in the center of the clamps in order to ground the remote -control unit to the steering post. Fasten the cable to the steering column and other points in order to prevent vibration and interference with the operation of the car.
11. Connect the two -conductor shielded cable to the battery, the BLACK wire always connects to the GROUNDED terminal of battery and the YELLOW wire always connects to the HOT terminal of battery regardless of polarity. (Re -read and check paragraph 7.) It is advisable to run this cable as directly as possible to the battery, keeping away from the engine compartment and other high tension wires. Grounding the cable as often as possible along its entire length reduces motor noise and is rec- ommended. Poor connections at the battery terminals cause noise; therefore, clean the terminals and make' good connections. (Connections to the ammeter are not recommended, in general.)
12. Before connecting the antenna, check it for a possible ground. If ungrounded, connect to the antenna lead of the radio by splicing a good connection, taping the joint and sliding the section of insu- lated tubing over the connection. In the event that the antenna lead-in is shielded, do not neglect to connect the shielding to the shielding on the antenna lead from the set. A word of caution here: Do not run the antenna lead-in thru the engine compartment and keep it away from all high-tension parts and leads. Ground the shielding of the antenna lead-in along its entire length, if possible.
13. Turn switch -key halfway in remote control unit. The dial should light up immediately if every- thing is correct. Turn volume control (small knob) clockwise to a position for loud volume and when the tubes are warmed up, turning the station dial (large knob) will tune in stations. Adjust volume by the volume control knob, never by detuning the station, as this ruins quality. The separate, delayed automa- tic volume control will counteract fading and blasting and requires little or no adjustment by the manual control.
14. If the installation thus far has been carefully followed, starting and running the motor causes very little interference generally. However, the amount of motor noise WITHOUT SUPPRESSION may be noted as a check on a good installation.
15. Fasten the condenser supplied for generator -noise -suppression by slipping the grounded lug of the condenser under a screw in the generator frame. Connect the live lead of the condenser to the gene- rator side of the cut-out relay mounted on the generator (connecting the live lead to the battery side of the cut-out relay is more effective in some cases. This may be determined by test.)

16. Fasten a spark plug suppressor to each spark plug (see Figure III) and the distributor suppressor in the head of the distributor. Fasten the suppressors firmly to the plugs and to the leads so that the connec- tions will not shake loose and ground. If special types of suppressors are required for certain cars, these may be obtained.
17. In general, this should suppress motor noise effectively. However, an auxiliary suppressor condenser connected from ground to battery side of ammeter may sometimes prove effective. (See further details under "Notes on Ignition Suppression.")

ADJUSTMENTS The receiver was carefully adjusted and aligned when it left the factory. Under no conditions should
these adjustments be disturbed unless there is no question that it is absolutely necessary.
Intermediate -Frequency To line up the Intermediate Frequency Amplifier, use a good modulated oscillator giving 172% K.C.
and a rectifier type output meter. Connect the oscillator output to the grid cap of the 6A7 and ground. Connect the output meter across the voice coil of the speaker or across primary of speaker transformer.
Ground the antenna lead and turn the tuning dial so that no signal is received (other than the test oscil- lator), with the volume control set at maximum volume.
Using the smallest output from the test oscillator to get an output reading, adjust the double -tuned input transformer and the single tuned output transformer for maximum output. It is preferable to use a non-metallic screw driver for this purpose. (See Figure IV.) Radio -Frequency
To line up the R. F. section, due to the extreme sensitivity of the receiver, use only a high-grade oscillator. Couple the oscillator through a standard dummy antenna to the antenna lead and ground of the receiver. Attach the output meter to the voice coil of the speaker and align the trimmers on the variable condenser for a weak high frequency signal (between 1350-1450 K.C.). Readjust the trimmers to get accurate settings. (See Figure IV.)
If a high grade oscillator and output meter is not available, it is suggested that the alignments be made on broadcast. Tune in a weak station between 1350-1450 K.C. and align the trimmers carefully. Readjust the trimmers as above.

that line up under these conditions and slip a lockwasher and nut on this bolt. Finally fasten both bolts securely so that the control head will not turn. Bond the cables at numerous points along the steering column to eliminate vibration and prevent interference with the operation of the car.
* * * * *
Paragraph 13 of the same section should read: 13. Place the switch -key in the slot provided for it and. turn clockwise until a snap is felt and the
dial illuminated. The light will indicate that the receiver is properly wired and ready to operate or ready for advance in installation procedure. Turn the volume control completely clockwise by means of the switch key to the maximum volume level. When the receiver is warmed up (this will be indicated by noise) tune a station carefully to resonance by means of the right-hand knob. Re -adjust the volume to a
satisfactory level. Never attempt volume attenuation by de -tuning the station, as this will distort the qual- ity of tone translation. The separate, delayed -automatic -volume control incorporated internally will tend to counteract fading and blasting, retaining the volume at the level determined by the manual volume control.
The illuminated dial and the tuning control mechanism are mutually self -aligning. If the calibration of the dial does not check reasonably well with the frequencies of the stations received, it is only necessary to turn the tuning control knob slowly clockwise until it stops. If the dial pointer is at the extreme counter -clockwise position they are aligned. If not, turn the knob slowly, counter -clockwise, until it stops and the dial is completely clockwise. If either or both these instructions are carried out the cal- ibration should check.
FIG. IV (Substitute for Fig. IV. now appearing in "Service Manual".)
THE FOLLOWING NOTES APPLY TO THE SERVICE SECTION
If it becomes necessary to disconnect the remote control unit; progress by loosening the two set screws which clamp the volume control cable to the lower stud on the receiver case, and by pulling the cable totally out of the recess provided for it. To detach the turning control cable, remove the cover of the receiver box and loosen the set screws which hold the cable to the worm gear drive. Unbind the two set screws which hold the cable to the receiver box and pull the cable out. Lastly, remove the bot- tom of the set and unsolder the two connections for the pilot light, pull it out of the grommet and the operations are complete.
To replace the control unit, it is only necessary to reverse the above process, being sure that the "tongue" of the volume control cable slips into the slot provided for it. This may be accomplished b' rotating the volume control knob slowly, and pushing the cable in simultaneously until the tongue en- gages the slot.
Replacement of the fuse in the event of a burn -out requires a removal of the floor board of. the car. Remove both cables from the battery and unlock the fuse receptacle in the yellow- lead, the fuse should drop out easily. A fuse of 10 ampere capacity, as indicated on the defective fuse, should replace it. The cause for the burn -out of the fuse should be determined before a new one is put in.
TONE CONTROL ADJUSTMENT
The adjustment as the receiver leaves the factory is set for full register reproduction. This is
recommended for closed cars and for vocal programs. Turning the control clockwise brings up the low
tones and is recommended for open cars and musical programs. Incidentally in this position, static and
other noises are decreased greatly. Do not turn clockwise more than necessary as definition of speech
may be lost due to the attenuation of higher tones by the car interior.

ADJUSTMENT OF LONG -WAVE PADDING COMPENSATORS
Two (2) of the compensators are located on the right side of the chassis and one in the front as indicated in the sketch. These compensators can be readily identified by the red mark placed on the adjustment hole.
1st - Turn the band selector switch to the long - wave position and adjust the carrier fre- quency output of the signal en erator to 856.6 meters (350 kilocycles).
2nd - Set the calibrated dial of the Receiver to read 856.6 meters (350 kilocycles).
3rd -- With the aid of a 1/4" (#4) socket wrench, adjust all three (3) padding compensators in the order marked in the sketch.
ADJUSTMENT OF LONG -WAVE OSCILLATOR SERIES CONDENSER
The long wave oscillator series condenser can be ad- justed through the hole in the side of the chassis as indicated on the sketch.
1st - Adjust the carrier frequency output of the signal generator to 1999 meters (150 kilo- cycles).
2nd - Set the calibrated dial of the Receiver to read 1999 meters (150 kilocycles) .
3rd - With the aid of a 1/4" (#4) socket wrench, adjust the long wave oscillator series con- denser until a maximum output signal is in- dicated on the output meter. To insure per- fect adjustment it is permissible to "rock" the variable condenser back and forth in order to follow the maximum signal output.

On the above, type I has two lugs. Type II has three leads and a red lead connects to a 400 volt section, a brown lead to a 200 volt section and the black lead is common.
Type III condensers have four leads. A red lead connects to 400 volt sections and a brown lead to 200 volt sections. Thus a 400-400 condenser has two red leads and two black leads, a 200-200 condenser has two brown leads and two black leads. The black leads are not on non in type III.
Wound Resistances in Fada Sets
Wire wound resistances used in .Fada receivers are identified by spots of color in accordance with the list- ing below. If you wish to order any of these resist- ances, be sure to specify both the part number and the value of the resistance in ohms. Your careful attention to this detail will result in our being able to give you much prompter service.

MODEL 94 Notes FRANKLIN RADIO CORP.
ALIGNMENT OF FRANKLIN MODEL 94 ALL -WAVE RADIO RECEIVER
Receiver should be circuit tested, and any high or low voltages should be cor- rected. This will reasonably insure the correct use of the resistors. However a visual inspection of the resistors and condensers should be made so that the alignment operations which are to follow will not be frustrated. A table of voltages which are to appear at the various terminals is appended. When cir- cuit testing is completed, proceed as follows:
(1) Set up signal of exactly 450 Kc, 30% modulation, 400-1000 cycles, oscillator to be very stable.
(2) Either apply high resistance voltmeter (AC) across plates of 59 tubes, or insert 15 MA DC Meter in the common cathode lead of the I.F. tubes (in lead to rotor of sensitivity controll,or if tuning meter is used simply observe tuning meter variations.
(3) Apply I.F. Ose, signal lead to grid or #2 I.F. tube.
(4) Adjust trimmers on #3 I.F. Transformer for max. signal and max. reading on sensitivity indicators.
(5) Apply I.F. Oec. signal lead to grid #1 I.F. tube and repeat operation #4 adjusting trimmers on #2 I.F. Transformer.
(6) Apply I.F. Osc. signal lead to antenna post and adjust trimmers on #1 I.F. Transformer and observe as in #4.
NOTE: Speaker is never disconnected so that audible signal is always present to aid peaking operations,
(7) Set wave band selector switch on B.C. Band (Farthermost clockwise position).
(8) Set tuning dial at 1500 Kc., checking that dial reads 100 when gang con- denser is completely closed,
(9) Apply 1500 Kc. Osc. signal (30% mod. 400-1000 cycles) to ant-gnd posts.
(10) Adjust trimmer on osc. section of gang condenser (section #1) for maximum signal.
(11) Adjust trimmer on first detector grid coil (Trimmer on section #4 of gang) for max. signal.
(12) Adjust trimmer on B.C. Preseloctor circuit (Trimmer on section #3 of gang) for max. signal.
(13) Sat tuning dial on 570 Kc. and adjust osc, signal to exactly 570 Kc.
(14) Adjust serties osc. padding condenser for max. signal (condenser C-3 on circuit diagram) (this condenser is located beneath chassis but is ad- justed from top of chassis thru hole in chassis. It is the trimmer lo- cated nearest to front of sot).
(15) Check peaking at 1500 Kc and make minor adjustment if necessary repeating operation 10.
www.americanradiohistory.com
FRANKLIN PAGE 4-11
FRANKLIN RADIO CORP. MODEL 94 Notes
(16) Check alignment at about 800 Kc to see if osc. and 1st det. are tracking.
(16-A) If when checking alignment at 800 Kc. and it is found that 1st det. does
not track with oscillator, necessitating an increase of trimmer capacity
on section 4 (also then on pre -selector section #3) then proceed as follows:
(a) Turn dial to 1500 I;c.
(b) Loose set screw on dial and turn dial on the condenser shaft
about 1 or 2 degrees counterclockwise and re -lock with set screw.
(c) Then proceed with operations #8, #9, #10, #11, #12, #13, #14,
#15 and #16.
Alignment should now be better at 800 Kc. or perfect. If not, repeat
operation set down in #16-A. Of course if in 16-A it was found that trimmer
condenser had to be reduced in capacity on section #4 (also then section
#3) then reverse the direction in which the dial was slipped on the gang
cond. shaft (move it clockwise in this case). Repeat the same operations
as outlined in 16 -A -c above.
(17) Move band selector switch to next higher freq. band (1550-4200 Kc.)
counterclockwise one notch.
NOTE: AFTER COMPLETION 0. OPERATION 16-A DO NOT TOUCH TRIPS ON SECTIONS #1, #3, and #4 OF GANG CONDENSER.
(18) Set up 4000 Kc. Osc. signal and connect leads from oscillator to ant-gnd
posts on set. Turn dial of set to max. signal (will be close to 0 or
1500 Kc. on tuning dial).
(19) Adjust 1st det air -trimmer (located on control panal, second knob from
left) for max. signal. If max. signal is secured at either extremity of
this control travel, than it will be necessary to make coil adjustments.
(a) If this trimmer peaked or attempted to peak at its max. capacity
then 1st dot coil lacks sufficient inductance (too few turns or
coil diameter incorrect). .
(b) If this trimmer peaked or attempted to peak at its min. capacity
(farthermost counterclockwise position) then 1st det. coil has
too high an inductance (too many turns). Remove 1 turn and re-
peat operation 19 until this first detector trimmer peaks the
4000 Kc. signal at 1/4 of its total travel from its farthermost
counterclockwise position.
(20) Set up oscillator signal at 1550 Kc. and turn tuning dial to farthermost
counterclockwise position (max. capacity).
(21) Adjust series osc. trimmer (C-2) (second from front of set, located be-
neath chassis but adjustable from top of chassis) until max. signal is
secured. 1st dot. air -trimmer should peak this 1550 Kc. signal some-
where in its range.
NOTE: If in operation #18, tuning dial did not pick up 4000 Kc.
signal at 10 or nearly 10 on dial, then oscillator coil for
this bind is in error having a wrong number of turns. This
difficulty must be corrected before proceeding with operations
#19, #20 and #21.
(22) Move band selector switch to next high freq. band (CC one notch)
(11000 to 4200 Kc.).
www.americanradiohistory.com
l'AGE 4-12 FRANKLIN
MODEL 94 Notes FRANKLIN RADIO CORP.
(23) Set up oscillator signal at 11000 Kc. Move tuning dial and gang condenser
to f;_rthermost clockwise position (min. cap.). Adjust cap. C-1 for max.
signal. (For operations which are to follow sut must be standing on
LEFT END. Condenser (C-1) is mounted on rectangular coil and snitch shield
beneath chassis.
(24) If 11000 Kc. signc.l cannot be tuned in with gang condenser at min. cap.
even after adjusting C-1, than osc. coil inductance is either high or low.
If inductance is lo -7 then 11000 Kc. signal cin be tuned in by increasing
g:ung cond. cap. (rotating gang). If osc. inductance is too high then this
fact cin be determined by varying Oscillator signal to some lower frequency
until signal is audible in receiver.
If this osc. eo.il inductance is incorrect, ermine the coil for correct
turns and diameter. Inductance c.,n be lowered by sliding last turn or last
2 turns away from rest of turns of coil.
(25) Check at what position the 1st det. air -trimmer peaks this 11000 Kc. signal.
Max. signal should b3 obtained .at about 1/4 total travel of this condenser
from its min. cap. setting. If this does not occur, then first det. coil
has wrong inductance value and must be adjusted by sliding end turn or turns.
Sliding turns outward away from main body of coil decre_ses inductance.
(26) Set up 4200 Kc. Osc. signal and move tuning dial and gang to Max. Cap.
Signal should be heard close to 100 on dial. Check 1st det. trimmer to see
that it peaks this 4200 Kc. signal within its tuning range.
(27) If in checking in #26 the 4200 Kc. signal cannot be heard (receiver does
not tune to 4200 Kc. signal) then the osc. coil inductance for this band
is too low and consequently C-1 in operation 24 was adjusted to too high
a capacity so that the facts in the case are that the osc. inde is too low
and distributed cap. too high. Therefore add 1 or L turn to osc. coil and
repeat operations 23, 24, 25 and 26.
(28) Check 1st det.trimmer at several points in this band. to see that it peaks
properly.
(29) Move band selector switch to next higher freq. band (22000 Kc. to 11000 Kc.)
(farthermost.CC position).
(30) Set up osc. signal at 21800 Kc. and move gang condenser to min. capacity
setting. Adjust trimmer on #2 section of gang cond. until signal is heard.
(3.1) If signal cannot be tuned in then osc. coil has too high an inductance and
must be corrected and same procedure followed as in #24 except that in this
case higher frequencies are used.
(32) Peak 1st det. trimmer at 21800 Kc. signal. (Be sure that #5 trimmer is set
at min. cap.). Should peak at 1/4 trimmer condenser travel from min.
setting. If this does not occur then and. of 1st det. coil is incorrect
and must be corrected. If air -trimmer closes more than 1/4 its travel the
inductance of 1st det. coil is too low .,aid conversely too high if trimmer
cond. does not close 1/4 its travel. Adjust and. of coil by sliding turns
inward or outward.
www.americanradiohistory.com
FRANKLIN PAGE 1-11
FRANKLIN RADIO CORP. MODEL 94 Voltage, Notes
(33) Set up osc. signal ut 11000 Kc. and move tuning di:a and cond. toward max. cap. At 100 or close thereto the signal should be heard. Be sure the signal received is the fundumental of osc. First det. trimmer should peak within its tuning range. No trouble should be encountered here un- less some high distributed or lumped capacity has been introduced in 1st det. ircuit which should not be present. This must be corrected if 1st dot. trimmer does not peak correctly at 11000 Kc. signal freq.
(34) If signal is received at a much lower (5 to 10 div.) than 100 on dial then osc. coil Inductance is too high and should be reduced. Then re- peat operations PO, #31, #32, #33 which will give a high capacity set- ting on trimmer on section #2 of gang.
(35) Check air -trimmer of 1st det. in various settings of gang between high and low freq. extremes to see that trimmer peaks at these points.
NOTE: When performing operations set down for the two high frequency bands no violent or sudden changes should occur in 1st detector air -trimmer settings. If such is experienced then operator has peaked trimmer on frequency on wrong side of oscillator.

The readings were made with the volume control in
the full "on" position.
*These voltages are the correct values. The average test kit will give much lower readings, (as low as 1/10 of these values) due to the low resistance of the meters compared to the high resistance included in the detector plate and screen circuits and the audio grid circuit.
When the volume control is reduced the

Filter Condenser The three leads from the main filter condenser are
connected as follows:
Black -to center tap of 280 plate winding Green-to filament terminal of 2110 socket Red -to +B connection on terminal strip
By-pass Condenser Assembly The condensers
tified, as follows:
1.0 mfd. .01 mfd. .05 mfd. .25 mfd.
incorporated in this unit are iden-
Green Leads Green and White Leads Black Leads Red Leads
Resistors 300 ohms-Orange, Black, Brown 400 ohms-Yellow, Black, Brown
10,000 ohms-Blue, Yellow 50,000 ohms-Green, White 100,000 ohms-Blue, White
TA megohm-Gray 1 megohm-Black 2 megohm-Black, White
Power Transformer Six leads are brought out of the transformer winding
on the side next to the terminal strip. Three are located on the opposite side. The transformer is connected as
follows:
Primary Winding-Stranded wires, terminal strip side
224 and 247 filaments-Heavy wires, terminal strip side
280 filament-Small wires, terminal strip side
280 plates-Two leads nearest front of set, oppo- site side
280 center tap-Lead nearest back of set, opposite side
The trimmer condenser mounted on the loud speaker must be adjusted for maximum volume.
Some types of the 247 Pentode operate normally with a blue glow. This action does not, therefore, denote that the tube is defective due to gas.
It is very important that no tube is removed from its socket with the receiver "on" as to do this will damage the receiver or the Pentode tube. Make sure that the lead from the top of each 224 tube to the variable condenser follows closely along the metal partition between the tubes. Oscillation may occur if this lead lies too close to the tube itself.
