Audio amplifier using mosfet

Audio amplifier using mosfet:

This is the dual-voltage Audio amplifier using mosfet. here used high and low voltage. 35 is the low voltage and 70 is the high voltage. 70-35-0-35-70 voltage is used in this circuit. this type of circuit can make a good watt. In this circuit two mosfet for the voltage. this circuit can make 250 watts using two transistors. 2sc500 and 2sa1943 transistors for the amplifier.

It needs a strong heatsink for the IC. 2sc5200 and 2sa1943 circuit
