Hi y'all!


First, what a great initiative! I'm really glad to have found this site, lots of good information, and this message board seems great.


Anyways, I have some problems with my old amp. It's a 410HD One-Thirty, serial nr B005655.


It started a long time ago. As I was playing, all of a sudden the sound faded away completely, replaced by a loud humming. Looking at the back of the amp, all the tubes were red hot! I switched the amp of instantly, and figured it had just done in, I was getting a new amp anyway.


However, a little while ago I decided to fire it up again to see what would happen. Sure enough, it worked! Just two problems... The sound cracks up very easily, even at a low volume. The tremolo is also dead. Switching it on doesn't do nothing.


Does anyone have an idea what might be wrong with it? Would it be too expensive to repair or what? I actually opened it up, and started twaking with a couple of small blue plastic potentiometers, which made the distortion even worse. Does it just need rebiasing? Is it time to change the tubes?


Thanks in advance!
