[BrackenMan]

I got it back on the bench. I haven't really gotten to look at the AVC, but I did get much of the hum to go away by disconnecting the pickup cable. I traced the connections to the volume pot and it's drawn correctly. It's a center tapped pot with the tap tied to B-.

I know about the B- switch, and I have confirmed that it's connecting correctly when it's closed.

Back with it tomorrow.
