Everything you need to build your own amp!


Basic Kit Includes: Blueberry Circuit Board and all components to make the amp, If you require speakers and grills you must add in options.

Soldering Iron and solder 

Helping hands are a good idea

  • Please be sure to read the kit instructions before you order. The kits are enjoyable but can also be challenging.

    You will have to identify components, calculate resistor codes (but are given in the instructions) and be able to solder them into place. Be aware that you are responsble for your soldering. 

    Basic kits require full assembly and any images of completed PCBs are for reference only.
