PCB 800W Power Amplifier circuit

PCB 800W Power Amplifier circuit:

This is the PCB 800W Power Amplifier circuit diagram. This diagram can make a maximum of 800 watts using MJ transistors. And 2sa/2sc can make 300 watts maximum. It’s a mono diagram. Here needs dual voltage. positive, negative, and ground voltage. Here can be used maximum 60-0-60 voltage. 

Speaker protection circuit diagram for amplifier:

This is the speaker protection circuit diagram for the amplifier. Every amplifier needs this circuit to protect the speaker. When the amplifier makes a problem, then the voltage comes out from the speaker line. And the voltage burns the speaker. For this, we need this circuit to protect the speaker. This circuit needs a 12-0-12 voltage to run. 

Speaker protection circuit diagram for amplifier

This is the Speaker protection circuit diagram. It can protect our Speaker from burns. 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.
