Great little project with minor inconveniences

Reviewer: from CARIBOU, ME USA

Works perfectly, but volume is set back from board edge far enough to prevent mounting. If you want it in a box, you'll have to add wires from pot to board. I did and it's perfect. Great sound with low distortion at high levels.

Good amp but keep a fan on hand

Reviewer: from Pasadena, CA, USA

Very good sound quality.

The amplifier IC (9-pin finned one) might overheat and thermal shutdown during use, especially with music with a lot of bass(?) Keep a fan on hand, typically hits about 50C-80C during use.

Tested with 2 4ohm speakers from an iHome iH16.
