Simple 3 Transistor Amplifier

Mini 3 transistor amplifier 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.Rangkaian 3 transistor amplifier is often used in simple portabe audio devices such as radios or small tape recorder. Mini-transistor amplifier circuit 3 is quite simple as shown in the figure below.
