Description
Physically about the same size as a standard 9V battery, this compact little amplifier delivers 0.5W of power into 8 ohms from a 9V battery. Ideal for beginners, experimenting and small audio projects. Designed around the LM 386 audio amplifier IC, the circuit uses only a handful of components and works from 4 to 12V DC.
Requires 1 x 9V battery (not included).
