300 Watt Quasi with 2N3773

Nbip300 with transistor 2N3773
This amplifier was designed to provide a use for the otherwise useless TO3 power transistors that many hobbyists have in their junk pile.  With good construction the module is capable of high quality performance and is rated to 300 watts into a 4 ohm load depending on power supply.  With the driver and output transistors specified it is limited to DC rails of +/- 70 volts.
