Product Details:
1: This power amplifier board is composed of four original 2SC5200 and four original 2SA1943 high-power Toshiba power amplifier tubes. Stable performance, strong power, very low noise, hard to hear
2: The rectifier filter circuit is 4 pieces of 50V4700UF filter capacitors and high-speed rectifier bridge silicon 25A.
3: Use high-precision metal film resistors and high-quality capacitors. The price does not have a heat sink.
Full-featured protection circuit
4: Because this board adopts direct coupling test amplification, the whole circuit has no coupling capacitance, which reduces the distortion to 1%. The overall sound test feel is (the low frequency is heavy and powerful, the midrange is full, the high pitch is sharp but not prickly, the current sound is very small, and the ears stick to the horn to hear) feel the fun of audio fever.
