100 watt amplifier circuit diagram using transistors:

It’s a 100 watt amplifier circuit diagram using transistors. Here, we can use any of the PNP and NPN transistors. 2sc5200 and 2sa1943 are used here. It’s a mono board. A positive ground and a negative voltage are required for this circuit. We can use a minimum 25-0-25 voltage to 50-0-50 voltage. The stereo needs dual circuits.

All resistors are 1/2 watts. mje340 and mje350 are driver transistors. These transistors also need a heatsink. So, uses 2 small heatsinks for the driver transistors. We can also change the driver transistors.

PCB Power Amplifier 1000Watt:

This is the PCB power amplifier, 1000W. This circuit can make 1000 watts using 8 transistors. Here, use 2sc5200 and 2sa1943 transistors. This pair of transistors can produce a maximum of 150 watts. We can use 50-0-50 voltage. We can use any of the PNP and NPN transistors.

Amplifier circuit diagram using driver board

Every amplifier needs a speaker protection circuit. This circuit also needs a speaker protection circuit to protect the speaker. If any cause the circuit to burn, then the voltage can’t burn the speakers. Here is the circuit diagram.
