Our best selling amplifier kit has had an upgrade and a facelift. Version 2.0 of our Pre-built Mono Amplifier Kit has a brand new IC and we've also made all of the components suraface mount for a neater design.

This audio amplifier kit can be used with any personal stereo equipment, including MP3 players. It uses the very polular LM836 audio amplifier IC which can output 0.7W of power. The kit is supplied with a PP3 battery clip and can run off any voltage from 4 to 15 volts.

Also supplied is a pre-built jack cable.

All that is required is to solder the jack lead, speaker & power clip to the board and you are good to go.
