ARC power amps blow resistors and bias circuits frequently when a tube fails, causing a return to the factory.
I had a D125 power amp burst into flames with the bias circuit board ruined one time.
Very costly repair.......sold the ARC and never went back to their tube power amps.
ARC preamps have very good reliability though.
