This is a basic 2.5W Artec amp circuit board with on-board on/off/volume potentiometer, with an included 9-volt battery connector. We include a basic sheet with wiring diagrams for this board. These make a great little amp, which can be housed in a cigar box, tin, or other small enclosure. If you are looking for more of a kit, be sure to check our our separate kit listings!
The amp board you receive will have clearly labeled 12" leads pre-soldered to the key points on the circuit board: speaker, battery, LED and input jack. All you have to do is connect the leads to your amp components and you're good to go.
You can also add a panel-mount gain pot to this circuit, if you aren't afraid of a little soldering. The video below shows how. Please note that you can damage/ruin your amp board doing this and we do not warranty any damage caused by following these steps!
