##  tell that to my buddy, who lives 5 blocks away from me. He has
a ten-tec hercules  SS  500 watt amp. Transistors are un obtainium.
There is no drop in replacement either. There is no way to even re-design
and rebuild the damned thing.   Its a door stop, worth nothing. Nobody
has been successful in getting a TEN TEC Hercules to work.  They
are all door stops.
