Kitronik Stereo Amplifier, Pre-built plus PP3 battery
Kitronik Stereo Amplifier, Pre-built plus PP3 battery
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.
This kit is also available in a kit version.
Note: You will only have to use the build instruction to connect the jack lead, power lead and speakers.

V battery/wall adaptor) though. You might get a slight echo from them as minor differences in the components might cause them to be very slightly out of synch. Then again I don't know if this would be noticeable. You might be able to get away with adding 2 extra speakers per kit by wiring them in parallel with the original speakers (wiring the extra speakers into the same place as the standard ones.), that way you would only need 2 stereo amps.
