hit up db-r.com they are pro's at fixing amps and they are licensed by just about every real true car audio business. I had no hesitation sending them my 4000 dollar amp to be rebuilt. It came back and I contacted Digital Designs and they asked I send them a copy of my reciept of who repaired my amp. After sending them the document I got feed back that the amp was fully warentied by DD. They are a great company and do great work. I am part of another all caraudio forum. Where the owner of db-r and main repair man is on often, He is a good guy! I strongly reccommend that you contact them first. and for me to rebuild my amp ( no offense but my amp is way bigger and better than yours meaning a lot more parts A LOT more, and to rebuild the amp with all new internals it was going to cost at best 350) I expect at the best your probably looking at around 150 at most to rebuild your amp and it be brand new!
