200W Amplifier Board DC 20V-90V Dual-voltage Mono Amplifier 1943 Plus 5200 Push-pull Tube Power Amplifier Board

Dual-channel support: Mono design; requires two boards to achieve dual-channel functionality

High-voltage-rated paired transistors: Utilises A970/C2240 paired transistors for pure, distortion-free sound quality

Wide voltage compatibility: Supports ±20V-90V power supply, adapting to diverse usage scenarios

Robust Output Power: 200W high-power output effortlessly drives 15-inch speakers

Classic Circuit Architecture: Employs a classic amplifier circuit design for stable, reliable operation, ensuring long-term fault-free use

This board is a monaural power amplifier board. For stereo operation, two amplifier boards must be purchased and used in a dual-channel circuit configuration. Features an A970/C2240 high-voltage audio push-pull dual differential circuit for voltage amplification, driving the A1837/C4793 medium-power push-pull transistors. The output stage employs A1943/C5200 high-power push-pull transistors. Wide power supply range accommodates ±20V to ±90V DC, delivering exceptional sound quality at 200W with ample drive power. Effortlessly powers 15-inch speakers
