Following up from this thread...
WHen i picked this up, it was in sad shape. The outside looked ok, but the insides looked terrible. Upon complete disassembly there was a nest of some klind, lots of spider webbing with a dead black widow and tons of what looked to be dirt, as if this was pitched out in the back yard!
Most of the solder joints on this amp are long gone. I had to re-solder almost the entire pre-amp board, and the front pannel tone board. This unit is also a victim of that nasty corrosive glue. i scraped off a bunch of it on the tone board that was beginning to eat away at components. I haven't even gotten to the driver board yet, but I'm sure it wil need resoldering as well.
It also appears that this was repaired at one time by a company called "Stereo Lab" THe driver transistors on the left channel board are not original.
The faceplate was in nasty shape, full of smoke stains, old tape that people had used as labels. Some idiot also seems to have tagged up the face with permenant marker labling his appropriate inputs as TV and something else. I was able to get 99% of the ink off, but a slight bit remains that is barely visable. If anybody has recomendations on getting permenant marker off, i would really like to know.
I hope to get this working properly again and give its beafy 110WPC a spin. I'll post more as I make progress.
