## 2 transistor amplifier circuit :

This is a 2-transistor amplifier circuit for 100 watts output. in this board used 2sc5200 and 2sa1943 transistors. we can use 20-0-20 voltage to 60-0-60 voltage in this board. it’s a mono diagram. It would help to always have the best quality transformer diode and capacitor to make a strong voltage. we can get the strong watts for the strong voltage. This is an audio transistor circuit diagram 2sc5200 and 2sa1943. it’s a mono amplifier. this amplifier can make 100 watts. NPN and PNP are used. We can also use other NPN and PNP transistors. here in this amplifier, we can use 20-0-20 voltage to 50-0-50 voltage and 4 amperes. For the stereo amplifier, we need a dual circuit. we know that voltage X amperes= watts. then 20 voltage 3 ampere= 20X3=60 watts. 30X3=90 watts. normally we can use 35-0-35 voltage to get a good performance.

All capacitors will be 100 volts. this diagram is a common amplifier diagram. and also an easy diagram.

## About 2SC5200

2sc5200 Polarity is NPN. Max Collector Power Dissipation is 150 Watts. The Max Collector-Base Voltage is 250 Voltage. Max Collector-Emitter Voltage is 250 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 17 amperes.

## About 2SA1943

2sa1943 Polarity is PNP. Max Collector Power Dissipation is 150 Watts. The Max Collector-Base Voltage is 250 Voltage. Max Collector-Emitter Voltage is 250 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 17 amperes.

Here we can see that that the maximum voltage is 250, which can throw the Emitter and Collector. The base can take 5 voltages. and the voltage ampere can take a maximum of 17.
