1 x Module
1. Dual channel support: Single channel design requires two boards to achieve dual channel functionality.
2. High voltage resistance tube: A970/C2240 tube is used for pure and undistorted sound quality.
3. Wide voltage adaptation: Supports ± 20V-90V power supply, suitable for various usage scenarios.
4. Strong output power: 200W high-power output, easy to drive 15 inch speakers.
5. Classic circuit architecture: adopting classic amplifier circuit design, stable and reliable operation, ensuring long-term use without faults.
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 pair tube dual differential circuit and A1145/C2705 voltage amplification are used to promote the use of medium power pair tubes A1837/C4793, and the output stage uses A1943/C5200 high-power pair tubes. Wide power supply range, 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, and 15 inch speaker can be pushed without pressure!

This is an upgraded version of the single-channel amplifier board 1943+5200 high-power transistor power amplifier board. The board is a single-channel power amplifier board; for stereo applications, two amplifier boards are required. The circuit design employs A970/C2240 high-voltage audio transistors in a dual differential configuration, with A1145/C2705 for voltage amplification. The drive stage uses medium-power transistors A1837/C4793, while the output stage employs A1943/C5200 high-power transistors; The power supply range is wide, supporting DC ±20V to 90V. As long as sufficient power is supplied, it can easily achieve an output power of 300W, with extremely strong driving power, effortlessly driving a 15-inch speaker.
Supply voltage: DC ±20-90V (recommended range: ±20V-75V; do not exceed the voltage limit; do not use a switching power supply.)
Output power: 300W (8Ω enclosure)
PCB board dimensions: 150mm x 75mm
