Have you tried getting in contact with the company who made the amp? I had a thermistor fail and I contacted MTX and they were very quick and helpful in pointing me in the right direction for a replacement. I'm sure the company will work with you in replacing the part.great I'm screwed...
I get the same Amps are made overseas bit...whenever I talk to someone from rockfordWell don't ask them to repair, ask for the part's spec based on the board notation.
Give them the board number and rev and then the placement number (TH301 in this case) and they should be able to do a parts lookup. I know that MTX was happy and fast to do it, hopefully Rockford would do the same.
