well, i finally got into this amp, life sort of intervened and kept me from working on it (crashed my bike, broke my collarbone and suffered nerve damage affecting my left index finger...fretting hand....sucks) but i just took a good look at this yesterday. turns out, it was in the tone circuit. the...
Seeing as there are only a few, re-valve the preamp section and firstly see if this helps. If not, consider recapping the electrolytics if you don't get far with basic circuit and component fault-finding when changing the valves. Having failed with the preamp valves and recapping, I would consider ...

I bought some corks at the hardware store and made new spacers for my grill. I moved it out about 1/4" or so, and the speaker didn't hit anymore. Dunno how the Dietz is mounted, but you can probably make some kind of spacer somehow. If it's screwed in w/the speaker screws, you might have to de...
i just had the original evm 15l from my dietz cab reconed as it suddenly stopped making beautiful noise. when i got it back, the gasket which surrounds the surround (confusing enough?) was 'shorter' than it had originally been. i called the tech who did the recone and said that the gasket which was ...
