Power amplifier-15V

Overview

To make speakers sound, audio power amplifiers are made. This project is a small experiment on audio amplifier. In this project, NPN and PNP power tubes are used for push-pull output, and transistors are used for first-level amplification. The input signal is 0.2V, the output is 0.5W, and the volume is adjustable.
