Well, actually "in" for repair. So we had a bit of a "problem" with a WOPL where the AC "in" actually came in contact with the chassis. Note to self - remember that series II amps have no room at the top edge of the backplane, especially when one reassembles the top cover!
Anywhoo… so that was fixed by rerunning the wire between the thermals and that was that. BUT.. seems I took out the preamp section of my AU-517. Got it all apart now, and checking out the main preamp board on the bench. All semi's test good, but in the process I noticed that there is a silkscreen error on one of them where Sansui got it "backwards" (confirmed by checking a few threads over at AK that show the orientation matching what I have, and of course it worked before!).
A little perplexed, I set it aside for the evening and got back to it this morning. And that's when I noticed this here... but, given the silkscreen error I have to wonder if that is a result of a "mod" done to it in the past, or.. if that AC actually had enough current running back through the RCAs to do such a thing.
Wondering if anyone else has either a AU-517 or AU-717 they can pop the bottom cover off on and see if they also have it like that?
