[Collins] 75A-4 Question

[Roger Shultz]

The answer to the mystery is that it was intentionally disconnected as part
of SB 2 (B) to reduce hum in the audio amplifier and originally went to pin
2. I finally found the other end neatly buried in the harness near V13.

Thanks to all for the bandwidth and assistance.

Does anyone have one on the bench and could look where a particular wire
terminates for me?

I removed the front panel to discover a white wire with black tracer near
the AF gain control came off of some point. It may have a slight blue or
green trace as well and likely terminates on the AF or RF gain controls. I
can't find the other end to know where it might be in the circuit either.

Any help would be appreciated.
