## 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.
