About this product


  • Boost a weak mono audio input
  • Create a one channel 1W amplifier
  • Simple to solder with 12 parts

Product overview

• Boost a weak mono audio input
• Create a one channel 1W amplifier
• Simple to solder with 12 parts
• Requires a 4-12V power supply (not included)

What can I do with this kit?
Amplify a weak signal up to a 1W output and run it to compatible speakers or headphones (not included). This one channel amplifier has adjustable input attenuation and a set gain of 50. The amp can fit in almost anywhere thanks to its compact 43 x 24mm board. With 12 parts, this kit is a great kit for those looking to get into electronics and audio enthusiasts alike.

What can I learn with this kit?
Learn about electronics and circuits and practise soldering with this kit. The kit uses resistors, capacitors, a microchip and a potentiometer. Learn how they are connected in a circuit and get practical experience soldering them. The kit amplifies the voltage and current of the input signal with the amplifier integral chip (a LM386N-3 chip) control. You can use the potentiometer to adjust the input attenuation. The signal is then transferred to a speaker or headphones (not included) which translate it into sound. This kit requires a soldering iron and may require wire cutters.

How easy is this kit to solder?
This is a great kit for any ability level. You can add to this kit by connecting a speaker or an easy-to-connect-to input. This kit requires a 4-12V power supply (not included).

Rated 5 out of 5 by from Bought one of these for a small project I found on the internet and its tiny! I had failed to solder once before attempting this project and the included tips taught me everything I needed to know. Used a small 15w soldering iron from Maplins which one of the Maplins store team recommended for beginners and it worked very well. I'm using it with a 9v battery and a 4 ohm 2 inch speaker i had for another project. It goes pretty loud with a 4 ohm speaker but i have to keep it on the lowest setting otherwise it distorts (6-8ohm speaker recommended). I have since ordered 3 more for several other projects including testing an 8 ohm speaker and creating a stereo setup. Great project very good value. Just make sure you get a 9v battery snap and headphone socket to wire it to.

Rated 5 out of 5 by from Despite the size of the completed circuit this little amp has a big mouth. On the plus side it is a very easy solder and the gain is set to about 50 courtesy of an RC couple between pins one and eight making it ideal for a small pocket amplifier for an MP3 player, voice recorder or even portable computer speaker. It works beautifully on a 9V battery and at the heart is the ever popular LM386, a good quality power amp IC. On the minus it does not come supplied with a battery clip, switch or speaker, and you'll need to buy those as accesories. I used this as an experiment in my Ampy3 box and it does a perfect job, as if the power output from the MP3 player is too great the module input signal can be attenuated by a pot. The speaker MUST be 8 ohm impedance- any more and you'll end up with a horrible mismatch that sounds like dustbin lids clanging and don't use it to power earphones unless you want to go deaf. All in all, for six pounds this is a very worthwhile kit.

Rated 4 out of 5 by from Bought this without realising it needs assembling, the picture shows it built up! Any way its not the first project I've carried out so I've set about assembling myself. Wasn't very impressed to find I'd got one resistor of the wrong value, luckily I managed to find one of my own. So check the contents before leaving the shop.

Rated 4 out of 5 by from I wanted a small amplifier for testing microphones and saw this one. very easy to assemble and worked ok on a 9volt battery. As I may have to modify the circuit to test various microphones I was surprised a circuit diagram was not included!

will this amplify a 40MHZ signal

Asked by: foxey
No, I am sorry but this will not work with a 40mhz signal, it is designed for audio signals.
