Tube Amp Building - Tweaks - Repairs / Re: Single tube Reverb headache
« Last post by shaun on July 24, 2026, 03:25:02 pm »The longer I build amps, the more respect I have for Leo Fender. Which is to say I believe basic lead dress and wiring is my problem all along, as was mentioned earlier.
Being relatively inexperienced with reverb circuits, I assumed the noise that was plaguing me was coming from the power voltage side of things, or maybe a transformer placement issue. I now believe it's simply that I can't run rev send and return lines where I had planned to, even if they are well shielded. I thought shielding would avoid possible noise issues when sending and returning rev signals to the front panel reverb pots. Well, apparently not. I guess I underestimated just how finicky those lines are.
Back to the drawing board for a re-design. When I resolve this, I'll re post.
