Electronics Help Care Amplifier circuit diagram This is an amplifier circuit diagram using 2 transistors. We can use any PNP and NPN transistors. like 2sc5200 and 2sa1943 or 2sc2922 and 2sa1216 or C5198 and A1941. We can also use TIP41 and TIP42. It’s a mono circuit diagram. We can use a 24-0-24 voltage to a 50-0-50 voltage. The output watts depend on the voltage and amperes. also depends on the transistors. If we use 2sc5200 and 2sa1943, then we get a maximum of 100 watts. Or if we use 2sc2922 and 2sa1216, then we can get 200 watts maximum. not only on the transistors. The main is the voltage and amperes. We know that Voltage X amperes = Watts. Using 35-0-35 volts and 2 amperes, we can get 70 watts outputs.
Every amplifier’s important thing is the voltage and amperes. A strong voltage and amperes can make a strong output in watts.
