Audio power amplifier

Audio power amplifier:

This is the audio power amplifier circuit diagram. It’s a stereo circuit diagram. Each side can make 100 watts. we can use 25-0-25 voltage to 50-0-50 voltage. We can use any PNP and NPN transistors. here used 2sc5200 and 2sa1943. This pair can make 100 watts.

This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
