My line voltage is 119.2-119.4vac. The number sort of fluctuates up and down a bit, and the longer I hold those two probes in the wall socket, the more nervous I got... lol.

I believe there's a fault with a 22 ohms resistor associated with the 1st Audio 6SQ7, or something very near to it. The closer I get a probe to it, the louder it buzzes. I think it's just boosting the signal through the air. But when the static goes dead, I can bump the resistor with the volume down and the noise comes back. I cleaned my potentiometers the best I could with a little bit of alcohol and WD-40 ( not the same day ) and I don't get all the scratchy noise so much, but I swear it seems like the tone control does nothing until you turn it to a certain spot, and there's noise all of a sudden. The volume pot does something similar, as the sound cracks in and out. It's silent, I jack it all the way up, it finally starts to crackle through.

I could swear I almost hear a signal through some of that static today...
