Feature:
1. Dual-channel support: Mono design, two boards are required to achieve dual-channel function.
2. High-voltage tube pair: A970/C2240 tube pair is used, the sound quality is pure and undistorted.
3. Wide voltage adaptation: Support ±20V-90V power supply, adapt to a variety of usage scenarios.
4. Strong output power: 200W high-power output, easily drive 15-inch speakers.
5. Classic circuit architecture: Adopt classic power amplifier circuit design, stable and reliable operation, ensure long-term use without trouble.
Product Description:
The board is a mono post-stage power amplifier board. If you need dual channels, you need to buy 2 power amplifier boards for circuit design and use; A970/C2240 high-voltage audio tube dual differential circuit and A1145/C2705 are used for voltage amplification, and the medium-power tube pair A1837/C4793 is used for promotion, and the output stage uses A1943/C5200 high-power tube pair. The power supply range is wide, DC positive and negative 20V-90V can be used, as long as enough power is supplied, it can easily reach 200 good sound quality, strong driving force board, driving 15-inch speakers, no pressure!
