Anybody help with F5?
 
I blew the left channel with to much gain from my preamp, on accident of course :)

Is anybody out there willing to help me get this guy fixed? The imaging is suffering just a tad with one speaker running :)

Post some measurements and tell us what you have done. That way someone might get some clues and will be able to help you.

Probably the best thing you can do is to measure voltages on as many nodes and write them in the schematics and upload that here.

If you just want to start swapping components, I would suggest you start with the small active elements (jfets and diodes) first. If your heatsink was too small, then you should swap the output transistors too.

Hi

If you look at the pcb of the damaged amp can you see any smoked or damaged components? Possibly output devices or resistors?
