[Collins] 75A-4 Question

[Roger Shultz]

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.
