Hello everyone!
Amp has power and sound, but the led-switches are dead, no light, pressing switch does nothing.
I can't switch channels or reverb on/off etc. It's currently stuck on crunch channel and all the knobs are working. All fuses are ok. On the back of the amp, impendance and damping switches work. The footswitch doesn't work either, no leds there either.
All tubes light up, and they have been changed from factory tubes, it sounds overall okay.
I suspect the BDM1, but I figured I could get some more opinions before I get a replacement part.
Where do I start my troubleshooting?
I have a little experience repairing and building amps.
