Electronics Help Care Amplifier circuit diagram This is a 4-transistor amplifier circuit diagram using 2sc5200 and 2sa1943. This circuit board produces 200 watts using 4 transistors. Here, use PNP and NPN transistors. We can also use other transistors like A1941 and C5198, or TIP41 and TIP42, or MJE15024 and MJE15025. This circuit runs with dual voltage. Positive, negative, and ground voltages. In this circuit, we can use a minimum of 20-0-20 voltage and a maximum of 70-0-70 voltage.
The amperes will be according to the transistors. 2SC5200 and 2SA1943: each transistor can take 1.3 amperes. Here, use 4 transistors; then 4 × 1.3 = 5.2 amperes. We can use a maximum of 5 amperes in this circuit, as this pair of transistors can make a maximum of 150 watts. then 2X150 = 300watts. This circuit can produce a maximum of 300 watts. 300/5= 60. Then we have to use a 60-0-60 voltage and 5 amperes to get 300 watts outputs.
