It's a good amp, the volume will have issues (noise/hiss), but all you need to do is remove the 75kohm resistors under the heatsinks. The audio quality is very good too.
exactly like the picture. ordered four and all four boards works with nice rich sound even with no preamp. can hear THD noise with the pot at mid way, but the pot is turn low and when pot turn max there is no THD noise which is perfect
