I didn't check the interconnects for corrosion. I did change the ICs that go between the amp and the preamp. allow me to clarify one thing: when I touch the preamp, SOMETIMES the buzz goes away, but not always. I figured that if I stopped the preamp from buzzing, I would leave that unit powered on while not listening. The amp, and everything else was shut off. That practice didn't work either. The buzz was there when I turned the amp on again.
Grounding A Preamp
I have a NAD 1155 preamp with a nasty buzz in the phono stage. It's not a phono grounding issue, because I checked that. After the preamp is on ~40 minutes, the buzz goes away after I touch the faceplate. So I am acting as a ground. Should I just run a wire from the preamp to a electrical outlet screw, or what? I am at a loss.
