so the OP just needs to find out if he wants to pay shipping and hope that all they charge him is $95.MTX charges a flat rate fee of 95.00 to fix most of their amplifiers, If you had a bigger class D I think they are 150.00, and I think they do board swap so you pretty much get a new amplifier in your old heatsink..
i think it was the 7801?The charge is that no matter what, atleast it was for the Monoblock I had and it was the one with 4 35a fuses 1700rms (4th or 3rd largest amp they make, I dont remember the model number off hand as its still sitting in the box from MTX lol.
