Dual channel support: Single channel design requires two boards to achieve dual channel functionality. <br/>2. High voltage resistance tube: A970/C2240 tube is used for pure and undistorted sound quality. <br/>3. Wide voltage adaptation: Supports ± 20V-90V power supply, suitable for various usage scenarios. <br/>4. Strong output power: 200W high-power output, easy to drive 15 inch speakers. <br/>5. Classic circuit architecture: adopting classic amplifier circuit design, stable and reliable operation, ensuring long-term use without faults.</div><br/><p>Product Description: <br/>The board is a mono post amplifier board, and if dual channel is required, two amplifier boards need to be purchased for circuit design and use; A970/C2240 high-voltage audio tube dual differential circuit and A1145/C2705 voltage amplification are used to promote the use of medium power tube A1837/C4793, and the output stage uses A1943/C5200 high-power tube. Wide power supply range, DC positive and negative 20V-90V can be used, as long as sufficient power is supplied, it can easily reach 200. Good sound quality, strong driving force board, and 15 inch speaker can be pushed without pressure!</p><p>Parameter: <br/>Supply voltage: Dual voltage DC ± 20V-90V (recommended to use below 90V, do not challenge the voltage limit). ) <br/>Power: 200W (undistorted power) <br/>PCB board size: 120 * 60MM (length * width)</p><p>Package Include: <br/>1X power amplifier board<br/></p></div></div><br/>
