Thanks for the prompt reply, Logan. I'll try that tonight when I can pull the chassis.

However, I am still wondering why I am getting any sound at all if the right-channel volume control is open. As I said in my post, I thought if the control was open, it would kill every bit of audio output and I wouldn't hear a thing, as this would be an open circuit.
