DIY Mono 300W 2SA1943 2SC5200 Home Audio Power Amplifier Board PCB

Product Details:

The circuit design uses A970/C2240 high-voltage audio pair tube double differential circuit, and A1145/C2705 for voltage amplification, which promotes the use of medium-power pair tube A1837/C4793, and the output stage uses A1943/C5200 high-power Toshiba pair tube. The power supply range is wide, DC ±20V~50V can be, the sound quality is good, the driving force is very strong, and it is very easy to drive a 15-inch speaker!

Power supply: DC ±20~50V (recommended: DC ±30V)

PCB size: 145*60MM
