Thanks again for the great info here. I was finally able to rescue the Sub-10 I bought. The guy before me had trashed the through holes for the FETs and the AC -DC diode bridge. Then I proceeded to trash the through holes for much of the PDC board, since I myself do not have the proper tools either... Anyway, after days of tracking down and repairing damage to the boards, and making a new PDC board, with integrated gate drive resistors, she's up and running with an upgraded Q5 and new Nichicon audio grade caps.

Edit: It seems this is actually C32. I see that value from a previous post. Thanks for all the info; I'll update this post if needed. Hello ngen33r, I have acquired a failed Sub-10 amp and rebuilt the PDC, recapped it, and replaced the FETs. It kept blowing the FETs, though, and measuring the output from the PDC to the FET gate it was 114V, so I figured something must've went wrong with the PDC rebuild. The PDC board was pretty crispy, so I fashioned a new one. Now the power supply seems to be working, the fuse is not blowing, but still no output and no blue LED light. I was testing voltages and suddenly C12 went up in smoke. Do you know what the uF value of C12 is?

Thanks ngen33r! Your info helped me repair my Sub-12 and it sounds great. It was blowing fuses; I rebuilt the PDC board, recapped it, replaced the FETs and TH3. I also found the input diode bridge was shorted, so after replacing that, it's back in business. I could not have fixed it without this thread.
