100 watts amplifier circuit board

100 watts amplifier circuit board:

This is a 100-watt amplifier circuit board, It’s a mono diagram in bridge mode. It can be used 15-0-15V to 25-0-25V. The TDA7294 is utilized in this configuration. for stereo needs dual circuit.

2sc5200 and 2sa1943 transistor amplifier circuit:

This is a circuit diagram for a 2SC5200 and 2SA1943 transistor amplifier. It’s a mono diagram. This circuit uses four transistors and can produce 200 watts. We can use a 25-0-25 voltage to a 60-0-60 voltage. positive, negative, and ground voltage. We can use another PNP and NPN transistor.

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.
