150 watts amplifier circuit diagram using 2n3055 and MJ2955:
This is the 150 watts amplifier circuit diagram using 2N3055 and MJ2955. We can use 35-0-35 voltage and 5 amperes. We can get the output to be 150 watts. It’s a mono board. For stereo, there is a dual circuit board. We can use another transistor. Here are the needed PNP and NPN transistors. Use another transistor following BCE.
The 2N3055 is a classic NPN power bipolar transistor. The transistor typically handles up to 15A of collector current and a maximum collector-emitter voltage of 60 Volts.
Collector Power Dissipation is 115 Watts. Collector-Base Voltage is 100 Volts. Collector-Emitter Voltage is 60 Volts. Emitter-Base Voltage is 7 Volts. Collector Current is 15 Amp. Operating Junction Temperature is 200 °C.
