Electronics Help Care Amplifier circuit diagram Amp circuit board using 2SC5200 and 2SA1943 transistors. It’s a mono audio amplifier circuit diagram. For stereo, we need to use a dual-board setup. here needs 35-0-35 voltage. positive, negative, and ground voltage. We can get a maximum of 100 watts of output.
We can use any PNP and NPN transistors.
Here is the best transistor amplifier circuit diagram

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 Maximum Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
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 Maximum 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 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.
500 watts amplifier diagram:
This is a 500-watt amplifier diagram. This circuit can produce 500 watts using 2SC2922 and 2SA1216. Those sunken transistors can make a good watt.
