This is a 100-watt amplifier circuit diagram using transistors. Here, use PNP and NPN transistors. 2sc5200 and 2sa1943 are used here. This circuit can make 100 watts of output. We can use a 25-0-25 voltage to a 50-0-50 voltage. We can use any type of NPN and PNP transistors. It’s a mono amplifier circuit diagram.

This is a 2-transistor amplifier circuit board using C5198 and A1941 transistors. It’s a mono amplifier circuit diagram. In this circuit, we can use a minimum 20-0-20 voltage to 50-0-50 voltage. We can get 100 watts from this circuit. We can also use another transistor. Here, the C5198 and A1941 transistors are used. Any kind of PNP and NPN transistors can be used here, positive or negative, and a ground voltage is needed in this circuit.
