This is basically an audio amplifier with one sound channel. Build the kit and connect it to an audio source using a mono jack. You will need two kits to make it stereo amplifier. The source can be your another FM radio project, mp3 project, etc.

You can also connect it to an FM radio, mp3 player, phone, etc. There is a potentiometer with a knob to control the volume and a medium-size speaker to listen to the audio. It takes about half an hour to build the kit. Basic soldering skill is enough to build it. This kit is good for electronics beginners and extremely easy to build.
