LM-3886 IC power Module
Stereo design using two boards can achieve balance power output;
68W cont. avg. output power into 4ohm = +-28V
38W cont. avg. output power into 8ohm = +- 28V
50W cont. avg. output power into 8ohm = +- 35V
Signal-to-Noise Ratio >= 92dB

board size: L80mm W30mm thickness 2.5mm
