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.

Can i listen to music using this?
Posted byon Thursday, 20 October 2016
Yes you can listen to music on this by plugging it into an MP3 player or similar. It doesn't play music on it's own.
can i connect just one 2W 8ohm 50mm full range speaker to this kit rather than have 2 speakers connected supplied with the kit
Posted byon Tuesday, 24 May 2016
You can connect one speaker to one of the outputs with no problem, the problem with this is you with lose signals that are sent to the other channel. You wouldn’t be able to connect one speaker to both output channels either as you could have a two different output signals which would either cancel each other out or damage the speaker/kit.
Can I connect my headphones as output?
Posted byon Friday, 20 May 2016
You can connect your headphones as an output as long as the impedance rating is 8ohms or higher.
I have purchased one of your pre-built kits 2141-JK and only need to plug in the IC but there is no notch on the IC to match up with the notch on the holder. There is writing on the IC which is - 2073D JRC E022B There is a round indent on the surface of the IC before the E on the bottom line. Which way should the IC be plugged into the holder ?

The round indent shows the top of the IC, this is the same as the notch. As such this should be positioned so it is the same side as the notch on the IC holder and PCB.
Hi. I recently purchased the Deluxe Stereo Kit. I soldered everything together and added a 9V battery to it but after I plugged the 3.5mm jack in to my phone I realized that the sound gets distorted when I increase the volume. I have tried using various devices and batteries but the results remained the same. Is there any way to fix this problem?
Posted byon Monday, 29 February 2016
There could be a couple of reasons for this, one of these reasons could be that R2 has a dry joint. It would also be worth checking that the wire connection one both the speakers are soldered and not just wrapped round. If you have any further issue then send a photo of the top and bottom of the circuit board to email@example.com
