[QUOTE="Spooney, post: 7811795, member: 584130"] These amps are generally very easy fixes. Pretty simple oldschool class ab technology. Your amp has a blown power supply and most likely shorted outputs as well whether they look blown or not. The hardest part for me about fixing these old orions is getting the clamp downs for the fets off of the fets themselves without destroying the ones that may still be good. Orion thought it was a great idea to use two sided tape between the fets and the clamp down bars. Even if you are very careful you will usually end up with several fets that have come apart at their seam. Good thing is though that the fets and outputs they use in these amps are very cheap so even worst case scenario if you had to replace all the heatsink mounted parts it would not be terribly expensive other than what somebody may charge you in labor. Several very reputable parts suppliers would be digikey,mouser,arrow,avnet,future electronics, and newark. I usually get the best prices from future,avnet, and arrow [/QUOTE]
