Smoke on my power amp

Have you opened up and look inside to see any visible damage, swollen electrolytic cap, internal blown fuse, maybe something obvious that may be able to be fixed local. Not a fan of shipping a heavy amp if avoidable. Long ago I had a speaker wire come loose on rev-a McCormack and saw smoke blew a internal fuse and had it fixed local from what I was told it caused damage on the rail.

Agree with almarg you need at schematic to simplify repair it can be done without but you may have to through parts at it that look suspect. If you can find an old school tech in your area that has year of experience trouble shooting you may be able to have it fixed for peanuts. If the 2 or 3 graying transistors or resistors are your problem you could be looking at pocket change in parts. You may laugh but the guy that works on my tube and solid state gear on the side works for the school board fixing media equipment and before that had a television repair business. He began his career in the 60's working at a television station. So finding someone local is possible. I don't think running amp without speaker hook up did it, positive and negative must have crossed, good luck you will get it running again.
