the mtx amp that blew randomly out of no where, i looked into it further, and its 3 FET's that are blown.

on the board they are listed as fet 105, fet 107, and fet 109. thats all that looks blown, the others look fine.

on the FETs themselves, all 3 read: F1505SB, 75339P.

where can i get 3 new FET's?

is db-r my best bet?

i emailed him, just thought i'd check here as well.

You will probably need more then just the FET's.

I have the same problem with my amp. I emailed db-r last Monday and havn't heard back yet. I also emailed a few others, with no responces either. Maybe its a busy time for the amp repair business? From the searching I've done it seems that all FETs should be replaced and not just the blown ones.
