Tube Amp Archive

I'd like to hear the amp turned up a bit more.

nevermind.

I could go for that, thyx, especially if we could find a large stock of older ones with the outer foil end marking. I think the 225 and the Mallory PVC types are similar too, both polyester. The outer foil marking on those caps was completely random. Years ago I checked a bunch of them with a scope...

geetarpicker, can you explain why you need the mixer for this setup?

Thanks!

Thanks, I appreciate that. On the Dumble I had those traces were not exposed copper btw, they were completely coated in solder. I wonder if Dumble did that to make the traces thicker?

You do know that the precision power supply board is a printed circuit board right?

Yes. I looked at it carefully when I still had the amp. It didn't look exactly "printed", more like home made, but it did have traces on the underside.

Thanks again.

Hehehehe, I thought you were asking what the circuit board was made from. That there is the blue RTV silicone goop. I am. I know the preamp board is Formica, I read up on it on this site. I'm wondering what the green power supply board material is. I realize it's probably not significant from a son...

Yeah, that right there.

Thanks, M Fowler.

Thanks!

markusw, that was very helpful, thank you.

Structo, there doesn't appear to be a bright cap on the Master Volume:

Thanks for your replies, everybody. I'm in Europe, so sending the amp to Two Rock for modding is out of the question. I was hoping you guys would have some ideas of what I could try, but maybe it really just is what it is. Mac Daddy, why do you suggest removing the bright cap? How would that be diff...

Hi guys, I have this Two Rock TS-1 amp I could use some help with. The amp sounds pretty good, but there are a couple of issues that bother me. First, there seems to be a big imbalance in tone when switching channels. If I adjust the bass control so that it sounds nice and full on the clean channel,...
