This is an assembled pair of an audiophile grade class A single-ended power amplifier. Output power is 10W. The quiescent current is 1.2A ! 

The sound is warm, detail with authentic bass energy that can hardly believe to be from a10W amplifier.

High quality components are used :

1.1% low noise , low temperature coefficient metal film resistors;

2. Elna RE3 series 220uF capacitors on the power rail;

2. matched pair IRF9610 at the input;

3. IRFP250N as the output MOSFET.

Supply Voltage & Current : +/-12VDC to +/-18VDC, 2A per channel

Board Dimension : 115mm x 50mm
