Application circuit diagram of KC580C color decoding circuit

The application principle of KC580C is: the color full TV signal is taken out by the band-pass transformer to take out the chrominance and color burst signals, and is sent to the circuit for amplification by the 15-pin. The chrominance signal passes through the two-stage band-pass amplifier in the circuit and enters the delay line.
