Mini Amplifier With 3 Transistors

Mini amplifier with 3 transistor is a simple amplifier with 50mW power drawn by 3 transitor. The series of three mini-amplifier transistors can be used for loud speaker 8 ohm load. Source voltage required to activate the mini-amplifier can be drawn from the batteries 9V.Circuit of mini amplifier with  3 transistor is often used in simple portabe audio devices such as radios or small tape recorder. Mini amplifier with  3 transistor circuit is quite simple as shown in the figure below.

Circuit Of Mini Amplifier With 3 transistor

Mini amplifier with  3 transistor circuit  includes type of amplifier OTL (Output Transformer Less). Mini amplifier with 3 transistor circuit is used for output coupling capacitors. Amplifier circuit is simple and suitable when used for audio amplifier experiment.
