Just to clear things out here - is it the same PSU that toasted both pcb's? I would definitely replace that one also, before connecting any other or repaired pcb. Or do you have 100% control of how your cabinet is wired? Old capacitors could die by age (they dry out eventually), but the amplifier IC death is more concerning... |

Totally different thing. You need this: http://www.ebay.com/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=la4460&_sacat=See-All-Categories |

Guess i better work on naming the threads better in the future.. |
