300W High Power Amplifier Circuit


This high power amplifier circuit with using transistor was designed to provide a manipulate in lieu of the otherwise useless TO3 power transistors with the purpose of many hobbyists experience at home their throw out megabucks.  With upright construction the module is gifted of tall 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 some degree of to DC rails of +/- 70 volts.
