The power supply range is DC + -15V DC to DC + -65V DC.

The recommended DC voltage is +-40V, which is ideal for household use.

The circuit design uses A970/C2240 high withstand voltage audio pair tube dual differential circuit, and A1145/C2705 for voltage amplification, promotes the use of medium power pair tube A1837/C4793, and the output stage uses A1943/C5200 high power T0shiba pair tube. The power supply range is wide, DC positive or negative 20V-50V can be, as long as enough power is supplied to easily reach 200W. The sound quality is good, the driving force is very strong, and there is no pressure to push the 15-inch speaker!
