I'm trying to repair a P. I thought the only problem was a disconnected input, but it seems to have some sort of grounding problem too. I've already got two wires going to the input. It's quiet when I'm NOT touching the metal parts, and buzzes when I AM. That's new to me. Anyone know what it could be?
have you checked everything out with an ohm meter? is your lead good? is your cavity shielded? sorry, but I have to ask the obligatory questions first, otherwise its like throwing darts blindfolded.
