Our pre-built version of our stereo audio amplifier kit allows you to focus more on product design.

The stereo amplifier kit is supplied with all the resistors, capacitors & IC holder fitted. Students just need to finish it by connecting the jack lead, speakers & power clip to the board.

It can then be used with any personal stereo equipment, including MP3 players. It uses a NJM2073D audio amplifier IC which can output 1W per channel. The kit is supplied with two speakers and a pre-made jack plug.

It has a PP3 battery clip and can run off any voltage from 2 to 15 volts. Output power at 9V is 1W per speaker.

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.

Note: You will only have to use the build instruction to connect the jack lead, power lead and speakers.


  • 1W per channel stereo amplifier.


Note: The following components have been pre-assembled and soldered onto the Stereo Amplifier PCB.


  • PCB Length: 58mm.
  • PCB Width: 35mm.
