Circuit diagram for an amplifier

This is an amplifier circuit diagram using a PNP transistor only. Here, we can use 6 transistors. All transistors are Positive transistors. 2SC5200 is used here. This is a mono amplifier circuit board. For dual-channel needs a dual circuit. We can use 25-0-25 voltage to 80-0-80 voltage in this circuit board. Here we are using 6 transistors; then we can use 8 amperes maximum. The output watts depend on the voltage. We know that voltage X ampere= watts. If we are using 50 volts and 8 amperes. then we can get 50×8=400 watts. 

Basic Specification for 2sc5200

• Transistor Type is NPN Power Transistor
• Transistor Collector-Emitter Voltage (Vceo): 230V
• Transistor Collector-Base Voltage (Vcbo): 230V
• Transistor Emitter-Base Voltage (Vebo): 5V
• Transistor Collector Current (Ic): 15A
• The Power Dissipation (Pc): 150W
• The transistor Gain (hFE): 55 – 160
• Transition Frequency is (fT): ~30 MHz. 

Basic Specification for 2sa1943

• Transistor Type is PNP Power Transistor
• Transistor Collector-Emitter Voltage (Vceo): 230V
• Transistor Collector-Base Voltage (Vcbo): 230V
• Transistor Emitter-Base Voltage (Vebo): 5V
• Transistor Collector Current (Ic): 15A
• The Power Dissipation (Pc): 150W
• The transistor Gain (hFE): 55 – 160
• Transition Frequency is (fT): ~30 MHz. 

This is an amplifier circuit diagram for 150 watts of output. It’s a mini audio amplifier circuit diagram using 2SC5200 and 2SA1943 transistors. It’s a mono audio circuit board. This circuit operates from 20-0-20 to 50-0-50 volts. Here, use 2 transistors. One is a positive transistor, and the other is a negative transistor.
