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.
