Wide power supply range supporting ±20V-90V, adaptable to diverse power environments.4. Powerful drive capability effortlessly handles 15-inch speakers with outstanding performance.5. Compact dimensions facilitate easy installation and compatibility with diverse audio systems.Product Description:This upgraded version features a monaural amplifier board (1943+5200 high-power paired tube power amplifier board). Designed as a single-channel power amplifier board, two boards are required for stereo operation. Circuit design employs A970/C2240 high-voltage audio push-pull transistors in a dual differential configuration, with A1145/C2705 for voltage amplification. Medium-power A1837/C4793 transistors drive the output stage, while A1943/C5200 high-power push-pull transistors handle the output stage. It features a wide power supply range, operating from ±20V to ±90V DC. With sufficient power supply, it easily achieves 300W output power, delivering exceptional driving force that effortlessly handles 15-inch speakers.Product Specifications:Supply Voltage: DC ±20-90V (Recommended: ±20V-75V. Do not exceed voltage limits. Switching power supplies are not permitted.)Output Power: 300W (8Ω enclosure)PCB Dimensions: 150mm × 75mmProduct Listing:1x Amplifier Board
