The LM368 amplifier chip is a versatile no-nonsense amplifier that needs only a minimum of extra components and therefore is ideal to build if you only need about half a Watt for projects. The circuit is quite straightforward. The audio signal enters on JP1 and is fed to the + input of the LM386 (pin3) via a 10k variable resistor.
