Thread: Pioneer SA-8800

  1. #1

    Default Pioneer SA-8800

    I've got a Pioneer SA-8800, cosmetically beautiful but dead in the water; blows the input fuse on the back as soon as it's switched on. The man I bought it from says when he last used it a couple of years before I bought it, it had an intermittent drop-out on one channel but was basically working. I'm perfectly happy with the deal; trying to make something that works but looks rough into something that looks good is almost impossible, but I'm not an electronics guy so once I get beyond the blindingly obvious, I'm lost. I'm good with fine instruments, but strictly mechanical stuff...........

    Is there anyone here who would repair it? I've been told on another forum that the likely culprits could be output transistors or a bridging resistor. If it's any help, in the fraction of a second before the fuse blows there's sometimes a faint flicker from the flouroscan display, and the capacitors charge up.

    Money doesn't have to change hands (but it could). I've a very nice Hacker Centurian record player with speakers available for barter. It needs a stylus but I've checked it on its tuner input and it works fine.

    Leo would be a good candidate, or perhaps Anthony. PM them and see what they say.

    Hmmmm "A bigger boy did it and ran away".............. I've sent a PM to Leo; no reply as yet. If I don't get a reply by Friday I'll try Anthony; I thought it not a good idea to try both at once in case they both said yes. What I've suggested is cash, barter (I have some bits and pieces I'd like to find good homes for) or trade swop. I'm ok with fine instruments (trained as a clock restorer) but lousy at electronics. Trade swop could be a "you repair my amp I repair your clock" kind of deal. That's one of my few late night ideas that still seems at least borderline sensible the following day

    Leo is on here from time to time, Anthony being a Super is on here more - I'm sure one of them will be able to help you.
