Ok,
I may have posted about this before, but I cannot find it. I have an old Princeton 65 SS amp. It is so noisy it's unusable. I've resoldered and then replaced the power caps and no change. I've resoldered all of the connections on the PCB and it made no difference ('refreshed' the solder). I've tried several guitars, cables, etc, and can not change the noise that way. It's 60-cycle hum. I have conditioned power to plug it into, a shielded studio (HAM radio operators made that a necessity. I basically have a Farraday cage in my basement HAHAHAHAHA!), have tried it in several circuits, in several locations (inside and outside of my house), and no change.
I've also swapped out the input jacks and have not had any luck. Fender SS amps are 'noisy' out of the box but this is insane. ANY help would be appreciated. I was an electronics tech in the Army and work in the industry now, so I'm not a novice, but I simply cannot figure this thing out! I love the amp (when it works) but am about ready to set it on fire! Thanks in advance!
