Generally, the only practical way to repair those it to replace the modules. All of the ones I've seen had too many problems to repair the modules. The ebay seller dealsbyjason may have the modules but he doesn't list them often. You have to contact him through ebay to see if he has them.

I have purchased boards from him before. Maybe I'll check with him. I'm really bumm'n since I bought this amp "new" and found that all of the 10uf caps on the smd board were leaking and one channel had ~10v across it's leads. I replaced all of the caps, two op amps, and three channels worked great. After the fix, the bad channel had ~6v ac and would produce static through a speaker. Then I shorted something (rookie mistake!!) as I didn't realize I still had power applied to the amp and now all outputs appear to have full rail voltage ~20v. Thanks for the input Perry. I'm not sure what I should do at this point. I can't even reference the fets in this amp: R8939 & R8943 (outputs) R8944 (power supply) 8932 (voltage regulator ??). I might be s.o.l. here..lol
