quam ut amplificator est:

This is quam ut amplificator est. This is a 4-transistor amplifier circuit diagram. This circuit diagram can make 300 watts using 60-0-60 voltage, 5 amperes. can use 25-0-25 voltage to 60-0-60 voltage. Any NPN and PNP transistors can be used in this circuit diagram. here use 2sc5200 and 2sa1943 transistor.

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.

Details about 2SA1943

2sa1943 Polarity is PNP. Max 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.

DIY driver circuit diagram:

This is the DIY driver circuit diagram for the amplifier. This circuit can make an amplifier using 20 transistors. This board is not an amplifier. It’s just a sound driver. It drives the sound to transistors. We can use any of the PNP and NPN transistors to make an amplifier. like 2sc5200 and 2sa1943. or c5198 and a1941. or TIP41 and TIP41. any of the transistors according to the voltage and amperes.

DIY driver circuit diagram

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.
