A friend of mine asked me take a look at her PM-1200. She was using it as a PA amp in a club, and it failed with copious smoke. I wasn't there, but I'd bet some band cranked it up until the distortion was unbearable, then backed off just a touch.
I opened it up, and it looks to me like the power transformer is fried - some of the windings look blackened. When I power it on, nothing happens, except there are soft crackling/popping/ticking noises from the power transformer itself.
Now, I'm not bad with tube gear, and I've had some limited success repairing solid state amps, but I found the manual and schematic, and clearly this thing is a little out of my league, so I'm hoping for some good advice from the collective wisdom here. I'd appreciate any answers to these questions....
- Is this even repairable? Are parts available? How much beyond the transformer is likely to be toasted?
- If it's repairable, is it worth it?
- Is it something someone like me (with substantial general electronics knowledge but no experience with Carver designs) could repair, or is this strictly for the Carver specialists?
- Is it worth anything in its present condition? Are there Carver enthusiasts who would want to acquire it on the cheap with the hope of repairing it themselves?
- Or is it just e-waste?
