Amplifier circuit diagram 200 Watts RMS audio output

Electronics Help Care October 27, 2026 Amplifier Diagram

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.
