Ok, I did some more tracing this weekend, and I think the Philco replacement candohm is causing the noise. When the noise occurs, the voltage at the top of the resistor rises, and at the other lug, the voltage decreses in sync with the noise. This is for the 3000 ohm section. So, I'm going to order some 25 watt resistors and install them in place of the 3000 ohm and 2240 ohm sections. This probably will fix the problem, but at the very least, remove one potential source of this noise.

Will post a follow up when done.
