Make a Great Sounding LM386 Audio Amplifier with Bass Boost
In this tutorial, I'll first show you how to make a basic audio amplifier with an LM386 IC to demonstrate the minimum parts needed to build a functional amplifier. Then I'll build a much better sounding amplifier by adding multiple de-coupling capacitors to the power supply and the input and output signal lines. Lastly, I will add a bass boost control to the circuit.
