I'm the original owner. It's been running my desktop system until I recently upgraded to a new desktop amplifier. The sale includes original box, 32V 5 AMP power supply, and upgraded LM4562 opamps inside.

Fosi Audio M03 Subwoofer TPA3255 Amplifier Mono Amp Full-Frequency Digital Bass. Condition is Used. Shipped with USPS Ground Advantage.

AIYIMA A07 power amplifier with TPA3255 chipset and improved op-amp chips (installed). Original chips also included. Also includes an upgraded 36V 4 amp power supply for a little extra punch. Manufacturers rated power is 300 watts x 2 channels but don’t expect that much RMS power. A realistic estimate with included power supply would be more like 64 watts per channel (128 watts total) assuming 90% efficiency of amp. Still has plenty of power for most modern speakers. I only used this lightly for a few months. I am selling because I upgraded to a class AB amplifier.

Stronger output power and a line output added: use TIs classic power amp IC 3255, each channel can output 300W(4?) and easily to drive all 4-8? passive speakers; stereo RCA output is added, easy to connect another amplifier or active speaker / subwoofer to build multiple channel system and enjoy wonderful home theater experience. Separate control for left and right channels: two balanced and volume knobs are designed for adjusting the left and right channel output indepedently, compensate for the left and right channel of all outputs and prevent the sound field positioning from deviating from the center position. Also with sensitivity knob of VU meter, easy to adjust and match better with different input signals.
