a bit lack of bass but powerfull amp. Manual say 12v to 18v dual AC, PCB is noted 15v to 22v dual AC. It seem that he have a DC output for a fan at the top left, near dual AC input. Perfect. Thanks.

Heat sink is not sufficient, min use four times the size. otherwise okay.

Kühlkörper ist nicht ausreichend, min die vierfache Grösse verwenden. ansonsten okay.
