How to add extra transistor

Electronics Help Care September 25, 2025 Amplifier Diagram

How to add an extra transistor? A Maximum transistor amplifier can add extra transistors, but it will not work if we don’t increase the amperes or voltage. If we want to add an extra transistor, then we have to increase the voltage and amperage. like the voltage is 35-0-35 and 3 amperes for 2 transistors. If we add an extra 4 transistors, then we have to add an extra 4 amperes. And the voltage can be 45-0-45 maximum.

The transistor circuit diagram is here

2-transistor amplifier circuit :

This is a 2-transistor amplifier circuit for 100 watts of 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 of 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 a 20-0-20 voltage to a 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 volts 3 amperes 20X3 = 60 watts. 30X3=90 watts. Normally, we can use a 35-0-35 voltage to get a good performance.

2 transistor amplifier circuit

Every amplifier needs a speaker protection circuit. This circuit also needs a speaker protection circuit to protect the speaker. If any cause the circuit to burn, then the voltage can’t burn the speakers. Here is the circuit diagram.

how to make a microphone circuit:

The microphone is a common subject in electronics. It’s so important for our daily lives. The microphone takes our voice and amplifies it. normally our voice is not so loud. The only microphone can make it loud. Everywhere needs this microphone. Without the microphone, electronics can’t run one step. To run or drive a microphone, we need a circuit driver to take our voice and make it a sound. really it’s wonderful things.
