Yes and the good news is my Centurion is up and running after I replaced the
two chips on the QSK board today.
However the fan still won't run so I need to fix that before using it any more.
I always used proper tuning but perhaps the fan failed and caused this. Either
that or something came loose during the repair. Mine has had a pot added to the
fan circuit.
Best regards - Bry Carling
