Mono 200W Power Amplifier Board, 2SA1943 2SC5200 Transistor HIFI Audio Amplifier Module, Class AB Rear Stage DIY Speaker Amp

The board is a single-channel power amplifier board. If you need a dual-channel one, buy two. The circuit design uses

A970/C2240 high-voltage audio differential pair tubes for dual differential circuits and A1145/C2705 for voltage amplification

to drive with medium-power pair tubes A1837/C4793 and the output stage uses A1943/C5200 high-power tubes

Toshiba tubes. The power supply range is wide, from DC positive and negative 20V to 90V, as long as it provides sufficient power

It can easily achieve 200W sound quality, strong driving power of the board, and no pressure when driving a 15-inch speaker!

Power amplifier board size: 120*60*45MM (length*width*height)

Real power: distortion-free power 200W maximum power 300W

Power supply: dual voltage, DC positive and negative 20-90V (the upgraded version has optimized the circuit and components, and can

be directly connected to high voltage. It is recommended to use below 90V, do not challenge the voltage limit.) Please leave a message in the order

letting us know what voltage you are using, so that we can debug the most suitable one for you. Effect
