Customer Review

Cute little Verstärkerchen that does what it should.
Caution: small is really small in this case! Interchanges and mounting holes are according tiny.
Best after datasheet ICs googling for wiring: PAM8403.

The amplification is sufficient to be driven by the line-out output of a PC or smartphone, the upstream connection of potentiometers is recommended.
NOTE: Not included is a screen-Elko, without this one obtains, depending on power strong background noise. On the back is for a platinum Elko space, lt. Datasheet it should be 470 uF, most still turn 100 nF film / ceramic parallel.
