Default PPI A600 amp blues...

Hey I can't find much info on my PPI a600 amp. It's been a rock solid performer since new in '92. It's been running two bazooka 10's in stereo mode from an alpine eq it's whole life with no problems. Last week it popped the internal fuse. Upon replacement of the fuse the amp "squeals" for five seconds then pops the fuse. I found my main ground to chassis was loose. I fixed the ground, took the amp's cover off, powered it up and watched two fets get hot enough to smoke. Nothing is visually damaged or fried. However, now when I power it up nothing happens at all. Hope I didn't destroy it.

I want to fix this amp. It is truly an old school jewel. I will send it in but have no idea if it is fixable as well as where a good repair shop would be.

Thanks for your help. JK
