[R-390] Audio Gain

[Anthony Casorso]

Thanks Chuck. I'm not sure where the ground is for the local gain control. I don't recall seeing it near the control so it is probably at the other end of the shielded cable. It happened again last night and I was more careful about it this time. I actually had to flip it to Standby and back in order to fix it. The control seems to be OK, not scratchy or erratic when it's working. When it's not working, playing with the control doesn't have any effect on the symptom. Only flipping that function switch seems to fix it. The ground that you and others have mentioned is the only thing that makes sense to me. Not sure how the function switch is involved.
