    Does anyone have experience repairing these vintage Integrated Amps? I have had mine in the shop now for 2 months and still not repaired. They first ordered output transistors from Mouser and we waited a month for them. They installed them and then they tell me they think something in the Pre Amp burned out! They are still diagnosing. They have all of the schematics and service manual.... Any suggestions? Thanks!

    I have heard of him, he's good but can't think of his screen name, starts with an "a" I think.

    I've rebuilt a few of them but the fellow in Iowa is the guru.
    First thing is to get it away from the shop and bring it home before they wreck some more stuff.
    As for the preamp, it likely has glue corrosion with at lease one capacitor eaten away.
    The last one I went through I had to replace something like 30 components from corrosion because the glue machine was set to kill that day and everything was doused with the crap.

    You're in excellent hands with either of these guys.

    This is really important. I'd retrieve as soon as possible, don't let them continue to work on it.
    More guesses and fails from the wrong tech = more work for the right tech.
