Sherwood XA-2200 schematic needed!

[matt_afm]

Hey, I bought this amp a few years ago from a friend for $20, had one burned out channel when I bought it, I used it in my Camaro, then my room with a 12-vold DC adapter. I went to sell it to a friend for the same $20, and it won't work, the "peak" light just comes on and stays on, whether I have anything hooked up to it or not. I opened the case and found a resistor to be damaged, so I went to Radio Shack, bought a new resistor, and soldered it in, amp still didn't work, "peak light still shined brightly... any ideas???

If someone out there as a schematic so I can check the rest of the internals, that would be great, I don't have the money to replace the amp so that is not an option for me, I would rather spend what money I have under the hood of my cars, rather than on audio systems (not flamin' you guys, just stating my opinion, I can and do respect the opinions of others)

Not going to be able to find a schematic easily and it will not be easy to repair unless your pretty good at electronics. Best bet if you are familiar with electronics (and I mean very familiar) would be to check and test each cap, resistor and component on the board. Can get to be a giant pain and really not worth the time for 20bucks, but hey to each their own.
