This is a 150-watt transistor amplifier circuit diagram using 2SC5200 and 2SA1943. This circuit can produce 150 watts of output. It runs on a minimum 20-0-20 voltage to a maximum 80-0-80 voltage. better voltage is 35-0-35 volts and 5 amperes.

It’s a mono audio amplifier circuit diagram. C2073 and A940 are driver transistors.
The circuit diagram is

This is an amplifier circuit diagram with 200 Watts RMS audio output. This circuit produces 200 watts of output. It’s a mono audio circuit diagram. For a stereo amplifier, we have to use a dual board. Here, we use 4 transistors. One pair of transistors can produce 150 watts of maximum output. In this circuit diagram, we can get 100 watts of output using one pair of transistors. Here, use 2 pairs of transistors. 4 transistors are used in this circuit.
