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.

in this kit i see the option for either 9v Battery or a 12 volt mains supply personally that is of which i prefer, i wont need to wire up the battery batter clip lead to the circuit board ? and i see their are two options of a 3.5 mm jack lead or a ipod lead i would rather have an female 3.5mm jack socket like what you would find in a guitar amp or in your car does the kit come with one of those or do you sell one on this website ? im sure it has a specific name doesn't it

Hi Jack, The kit works on when the jack socket for the mains power supply is plugged in it disconnects the terminal for the battery clip lead. As such you shouldn’t need to solder the battery clip lead in if you are only using the main power supply. With regards to the input I believe you are referring to a jack socket so that an input lead could be plugged into the amplifier, an example of this can be seen here, https://www.kitronik.co.uk/blog/how-to-make-a-practice-guitar-amplifier-with-a-volume-control. This would be fine to do, if you change the input lead for either a 3.5mm or 6.5mm jack socket that would be fine.
Do I need another component to enable it to be used with headphones. Presumably it needs to disengage the speakers and then divert stereo signal to another stereo jack output for headphones.

Hi Tony, You could connect your headphone as an output as long as the impedance rating is 8ohms or higher. If you still wanted to have the speakers connected as well you would need some way to switch between a speaker output and a headphone output. This would require additional components off the PCB.
Could you connect the Apple 8 pin charger to this circuit so that is would be able to both charge an apple phone and connect the music on the phone to the speaker?

Hi Maddie, Unfortunately none of our amplifier kits has the circuity built in to allow it to charge either a phone, IPod or MP3 player. Sorry.
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

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.
