Roland Metivier from Pasadena, CA, USA
Good amp but keep a fan on hand
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.

A customer from CARIBOU, ME USA
Great little project with minor inconveniences
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.
