Are you looking for a small audio amplifier circuit that’s not only cheap but also easy to assemble and can be done quickly? The idea presented here suits the need perfectly. It uses the IC LM386 which can be configured quickly by connecting just a couple of external components. The output power is not more than 1.25 watts which is reasonably powerful for low power applications as in door bells, FM radios, MP3 players, intercoms, etc. The amplifier is accompanied with some impressing features like gain control, bass control and auto offset control.
