Nice enclosure, is it something you can buy or did you make it yourself?

First attempt at a chip amp build. Decided to get some cheap DIY LM1875 board kits off ebay for the amps and a DIY rectifier board. Picked up a few of the transformers locally for a good deal about a year ago. Laser cut the enclosure out of thin plywood and acrylic. 3D printed brackets to hold all the sides together. Sounds pretty good for only $40 invested.

Love the look of the plexi top. Nice build. Wish I had a better look at the heatsink. A bit concerned it might be too small but the cab looks great!

I will kick this off with my newly finished Chip Amp and let the moderators decide if this should be a permanent thread or not.

This is an LM3886 based Chip Amp using PCBs from www.chipamp.com.

The tranny is a Piltron 160VA 22V transformer with 15000uF caps and snubbers.

For a more laid back sound, I went with Carbon Film resistors.

The results really surprised me. The Chip Amp sounds better than I expected and better than it should consider the cost.
very informative
