◈ 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.
