This is my LM3886 amp. I used the stereo kit purchased from chimpamp.com which came with the PCB's and parts for the amplifier and power supply. I added all of the parts you see mounted on the chassis and I salvaged the transformer and heatsink from a broken computer 2.1 system. The box is a wooden wine box. Wooden boxes look cool, but as many other makers have found, they are hard to work with as they have thick panels and don't ground. It was a fun build and now I know more about AC, transformers and rectifier circuits. The amp sounds good and is powering my garage speakers.
