Kitronik 3.5mm Jack - Deluxe Stereo Amplifier Kit

Note: There is a newer recommended alternative to this Amplifier kit that is very similar in features to this one. This new stereo amplifier kit is available here.

This deluxe amplifier kit can be used with any personal stereo equipment, including MP3 players. The kit has a volume control & power LED. It can be powered by a battery connected to the PP3 clip or a DC power module can be plugged in, in which case the batteries automatically disconnect and the power supply is used. The kit can be powered off a 2V to 15V supply, though the volume is better with a higher supply. It uses a NJM2073D audio amplifier IC which can output 1W per channel.

It works nicely off a 9V battery (not supplied) or if you want to run it of the mains why not try our 12V wall power unit.

This kit requires soldering.
