Audio Power Amplifier Project Report

Use 20v to 60v for operating this circuit.

Audio power amplifier project report. In this project we study the vacuum tube and audio amplifier circuits. It is built around popular amplifier lm386 ic1 an 8 ohm one watt speaker ls1 four capacitors and a few other components. A 6v battery is used to power this project. Author s prototype of lm386 based audio.

Lm386 based audio amplifier. This amplifier is mainly for the cd vcd and dvd players which are the most common audio players today. The input can come directly from a cd audio player or similar device and typical 8 ohm speakers are driven. In this circuit one ic 4558 and 4 power transistors are used with some discrete components.
