take the cover off the back and take pics. the real deciding factor if it is repairable, is the condition of the board, mostly. best prices i have seen, really, are right off the forums. there is a few on here, and another forum, and i generally don't have time to take some of that on. there are a few more popular shops, but the best bet is someone whoe does just amps, not a computer, or general electronics shops..... sometimes you can find a decent stereo repair shop that will be good, but generally, electronics/computer shops are setup for different sort of repairs, and priced for the industrial side, which can get real pricey
