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.

Posted by Luke, Friday, 16 September 2016 on product Stereo Amplifier, Pre-built

Question:

Where are the volume and on/off pieces? Are they separate? Does a battery box come provided and if so how big is it?

    Hi Luke, The stereo amp kit doesn’t have a volume control one, however you can add one by using a dual swipe potentiometer and connecting one side to the source input signal, the other side to ground and the middle to the input on the PCB. There is a section on page 4 in the following document which shows how to add a power switch to the circuit, https://www.kitronik.co.uk/pdf/2136_stereo_amplifier_essentials_2_0.pdf. Lastly the kit doesn’t come with a battery cage as it can be powered from a 9V PP3 battery, but it can run on a voltage range of 2-15V’s.

Question:

I have bought this kit, but I do not know how to construct the rest of the pieces. Are you supposed to cut wire for the speakers in half, or does the kit come with 2 and I'm missing a wire?
