All of the VCA modules are very susceptible to stray noise. On some
units, shielded wire was used for many of the inputs and outputs.
You might try just opening the panel and moving wires aside to see
if you can reduce the coupling between one input and the sensitive
high-gain circuitry of the other channel.
