Equivalent circuit
IF AGC filter connection
The AGC voltage is created by smoothing the signal
that results from peak detection by the AGC detector
at pins 17 (first AGC), and 15 and 16 (second AGC).
The video signal input to this IF AGC detector is a
signal that was passed through the audio trap circuit.
