RE: Inspecting a Fender Princeton Reverb guitar amplifier
I am a big fan of your amplifier posts. I hope to do some myself in the near future. I have a couple of I amps I am going to be doing some work on.
Thank you!
I think it would be pretty cool if you were to do a few of these posts! I look forward to seeing them.
I have a bassman 10 (I think I mentioned it to you before) that when you plug into the 'studio' side and turn the treble pot, there is a relitively quiet (but still pretty audible) oscillation that happens and changes frequency as you turn the pot. I need to figure out what is going on with it.
Well, that is an interesting problem! There may be a broken lead on one of the parts in that section of the circuitry, or possibly a capacitor way out of spec.
Yeah, it is all original. The I was going to replace all of the caps anyways and if that doesn't do it, maybe I will discover the problem in the process.
