This is a stereo high-power finished PCBA power amplifier board which is made of discrete components, and its maximum power is up to 300W+300W.
The input stage adopts American power differential transistors and medium power one for differential amplification to make its sound pure and soft. The output stage adopts 6 pairs of US WY2963/WK5688 power pair transistors, and 2 pcs high-precision temperature compensation one with constant current amplification designing, let its sound is more beautiful and delicate and sweet; And, the protection circuit uses imported Omron relay; RC component uses high-precision fever components to ensure the consistency of the materials used in the whole unit.
