I've been tinkering with amps for some years now and while I'm not on most of you guys's level, I can read a schematic pretty good and have done mods and such for most of my amps.
Something I've never been very good at is figuring out what is wrong when an amp acts up. This week I was tinkering with my VOM champ, some of you might remember me saying I rebuilt this thing. It was working ok and I was experimenting with swapping bypass caps and I killed it. I was getting no sound at all. I rigged up a poor mans signal injector with an old guitar tuner that had tones and traced it down to the preamp tube where I was working but I'm damned if I could see where the problem was. I must have shorted something out but couldn't see where. I ended up removing all the parts from the tube socket and remounting them and that fixed it.
Some of you may have read about that Quad sale I did and was asking questions about. The problem on that was a broken resistor lead under the cap can. I never would have been able to trace that down.
I've read R.G's debugging page, and have used those tips. I've never had any formal electronics training, I guess that would help.
Any other tips on how to get better at this?
