Electronics Help Care Amplifier circuit diagram Amplifier circuit diagram using MJ2955:
This is an amplifier circuit diagram using MJ2955. This board can make 200 watts using 2N3055 and MJ2955. 2N3055 is a positive transistor, and MJ2955 is a negative transistor. This is a mono circuit. This board needs dual voltage: positive, negative, and ground. This board runs with 35-0-35 voltage.

2N3055 Polarity is NPN. Max Collector Power Dissipation is 117 Watts. The maximum collector-base Voltage is 100 volts. Max Collector-Emitter Voltage is 70V. The Max Emitter-Base Voltage is 7V. The Maximum Collector Current is 15 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.
This is an amplifier circuit diagram using transistors. Here, the C5198 and A1941 transistors are used. We can also use other transistors. any pair of NPN and PNP. like 2sc5200 and 2sa1943. It’s a mono audio circuit diagram board. This circuit can deliver up to 400 watts. It depends on the voltage and amperes. If we use 35-0-35 voltage and 5 amperes. Then we get the output 35X5=175 watts. or 50-0-50 volts and 5 amperes. Then the output will be 50X5=250 watts.
This circuit needs a strong heatsink for the transistor. And the voltage should be good to make the best watts. We know that voltage X amperes Watts.
