Electronics Help Care Amplifier circuit diagram This is an amplifier circuit diagram using transistors 2SC5200 and 2SA1943. This circuit produces 150 watts. It’s a mono audio amplifier circuit diagram. We can use a minimum of 20-0-20 volts to a maximum of 50-0-50 volts. PNP and NPN transistors can be used in this circuit.
Basic Specification for 2SC5200
The transistor type is an NPN Power Transistor. Transistor Collector-Emitter Voltage is 230V. Transistor Collector-Base Voltage is 230V. Transistor Emitter-Base Voltage is 5V. Transistor Collector Current is 15A. The power dissipation is 150 W. The transistor Gain is 55 – 160.
Basic Specification for 2SA1943
The transistor type is a PNP Power Transistor. Transistor Collector-Emitter Voltage is 230V. Transistor Collector-Base Voltage is 230V. Transistor Emitter-Base Voltage is 5V. Transistor Collector Current is 15A. The power dissipation is 150 W. The transistor Gain is 55 – 160.

Low-pass filter for subwoofer amplifier:
This is the low-pass filter for the subwoofer amplifier. This circuit needs to make a bass amplifier. We also need to make a 2.1,5.1 audio sound system. This board makes only bass. makes only the low part. It has no mid-range or high-frequency part. It’s also a pre-amplifier. Its output is mono. The input is stereo, but the output is mono. This board runs on 9 volts to 15 volts. It needs a single voltage. For this, we can use this board in the car amplifier.
