PCB Power Amplifier 1000Watt:

This is the PCB Power Amplifier 1000Watt. This circuit can make 1000 watts using 8 transistors. Here, use 2sc5200 and 2sa1943 transistors. This pair of transistors can produce a maximum of 150 watts. We can use 25-0-25 voltage to 60-0-60 voltage. We can also use another transistor. We can use any of the PNP and NPN transistors.

Details about 2SA1943

2sa1943 Polarity is PNP. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.

Details about 2SC5200

2sc5200 Polarity is NPN. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.

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.

Amplifier circuit diagram using driver board:

This is an amplifier circuit diagram using a driver board. It’s a mono circuit using PNP and NPN transistors. It can make 600 watts of output using 60-0-60 voltage and 10 amperes. 60X10=600 watts. Here, we use 8 transistors. We can also use an extra transistor if we want. A maximum of 20 transistors can be used in this circuit.
