6v Audio Amplifier Circuit Diagram. Circuit diagram of the lm386 based audio amplifier is shown in fig. Connect the circuit diagram as in the one marked with amplifier with gain 20 and you get 20 fold the signal.

It is built around popular amplifier lm386 ic1 an 8 ohm one watt speaker ls1 four capacitors and a few other components. For splitting the signal you can use resistors for basic splitting. Before using this project test it using the 6v battery.

In this tutorial i ll show you how to build a great sounding audio amplifier with the lm386 low voltage audio power amplifier i built about a dozen different audio amplifier circuits with the lm386 but most of them had way too much noise popping and other interference.

This is my first successful vacuum tube project. The output of this small amplifier in which a 6v6gt output pentode is connected as triode is about 4 5 watts. Connect the circuit diagram as in the one marked with amplifier with gain 20 and you get 20 fold the signal. If you need exactly 6 you can play a round with the resistance on the input.
