IanFender Homebrew with JCM900PT question
I built a little Fender 50w type amp using a PT from a JCM 900 that I had layin around,this one has a 20+20v center-tapped that winding that I dont use nor have connected, (I have it isolated both the ground and the hot leads, ,however the amp has a low frequency hum when I crank the amp up and wonder if this unused winding in the PT could cause this somehow??
