    Oh no, feeling really gutted for you. I know how much work you have put into these Amps. No worries I'm sure it's only a minor setback.

    Well I got it apart already and the negative board has 2 blown Mosfets
    I have already matched a god pair out of my stash

    It looks like the J fet is gone as well but again I got plenty of spares, this is a bit more upsetting because it is going to be one less pair that I leave to my grand children's
    It should be back on later on
    Positive thing about it the speaker protection works
