Naroote Amplifier Module, 2.0 Channel Low Distortion High Efficiency TPA3255 Professional Class D HiFi Home Theater Digital Power Amplifier Board for HiFi Amplifier

First one had a bad ground that produced a hum so I ordered a second one and that one had static in lower frequencies in one channel.

Yet another version of the TPA3255 Chipset used in this. This one hasnt blown up when using 48v like 2 others have. These seem to cheap out on the voltage regulator chip, its been same component on two different versions of this CHipset in Chinese manufactured boards that gave up the ghost unecpectedly. This one seems fine and the Sound is excellent with this. I implememnted a Alps 27 Volume pot and installed in a nice aluminum enclosure. High end sound for peanuts.
