I got an original pork barrel I built a while ago and never got around to trouble shooting.
The issue is it has no effect, there's a minor change in the tone when its on but the pots do nothing and there is no modulation. My IC voltages are all over the place. the spreads are oscillating between those ranges. I can check voltages at transistors but I'm assuming this is plenty to start.
Also the BBD is getting very hot almost immediately after applying power
