200 watts audio amplifier circuit:
This is a 200 watts audio amplifier circuit diagram using 2sc3280. Only NPN transistors are used in this diagram. We can get a maximum of 200 watts from this diagram. Here, we can use 24-0-24 voltage to 45-0-45 voltage. The output watts will depend on the voltage and amperes used, because of voltage X amperes= Watts. if we use 35-0-35 and 5 amperes then the watts will be 35X5=175 watts.
Tip41 and tip42 are used as the driver transistor. tip41 is a positive transistor and tip42 is the negative transistor. it’s a mono diagram board.
This is the Speaker protection circuit diagram. It can protect our Speaker from the Burn. if the amplifier has any problem then this circuit can save our soundbox. Normally when the transistor makes a short circuit the voltage comes out from the speaker output line then this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is very important for protecting the speaker.
