Introduction
Amplifiers are the circuits that increase the input power of the system on the output side. Hence, audio amplifiers enhance the audio amplitude of input signals. And, through the gain of that audio amplifier circuit, you can comprehend the amplification at the output. How to make Audio Amplifier with 2SC5200 Transistor? We will see this in the following tutorial.
Designers classify amplifiers into pre-amplifier and power amplifiers. Power amplifiers are further divided into so many other types. Or you can say that The amplifier devices usually have two stages, a pre-amplifier that only amplifies voltage gain and not the current gain, and a power amplifier that causes a power modification of the audio signal. And, this article is about audio power amplifiers.

Audio Amplifier Circuit
Working Explanation
In this Audio Amplifier with 2SC5200 Transistor, when you give the 12V supply to the circuit and provide the input audio, the capacitor C1 blocks the DC component at the base of the transistor. And the potentiometer controls the input voltage. Now, the AC signal gets generated at the transistor’s base and acts as the control signal. The collector of the transistor is driving the speaker. Hence speaker generates the amplified audio.
