Features:
The whole machine is designed with aluminum alloy casing. It adopts imported materials and is tested and inspected in strict accordance with European standards.
The front stage uses one 12AX7 and two 6SN7 vacuum tubes; the driving part uses two 300B electronic tubes to amplify the rear stage.
The front stage uses a 274B (fishhook style) for rectification
The rear stage uses two 805A vacuum tubes for class A single-ended power amplification
Five groups of signal input A, B, C, (D) BALANCE, E (PREIN) This machine is specially equipped with balanced input function and pure rear function
Power on mute delay function, soft-start feature to prolong tube life (about 30 seconds).
Infrared function remote control
Use Japanese high-end potentiometer
Easy to install plug in vacuum tube shield
Peripheral power tube bias current adjustment function and power output level meter sensitivity switch
Soft, pure and sleek sound, suitable for listening to various types of music
