KS9C NTSC Chassis block

This part consists of Tuner and Saw-filter, etc . The tuner demodulate the RF signal to IF signal.

Saw-filter limite the bandwidth of IF to normally 6M bandwidth.Andthen 6M bandwidth IF signal input to UOC Chip.

Sound Amplifier Diagram

OTL(Output TransformerLess amplifier) AMP

- An AMP that does not use output transformer.

SEPP(Single Ended PushPull) circuit is used

and ouput impedance is low. Therefore,

speaker is connected directly.

BTL(Bridge Tied Load) AMP

-2 AMPs operate 1 channel. An AMP from

one channel amplifies (+) and the other

amplifies (-).

OCL(Output CondenserLess) AMP

- An amp that does not use output condenser.
