*Output ; 8W

 

*Output ; Type A1 Class

 

*Output ; Impedance 4Ω 8Ω 16Ω

        

*input Sensitivity : 0.8V

 

*input Impedance 100K

 

*Bias electric current is practicable to make free adjustment from mini 50mA to maxi 78mA and is set at 68mA When delivering goods

 

*Vacuum tube applied : Microwaves vacuum tube 12AX7, Drive Vacuum Tube VT137,

Output vacuum tube ; 300B,

Rectifier vacuum tube ;5U4GB

   

*Hum : 0,0002V

 

Sound loss has been minimized by reducing power loss through B-voltage drive after mounting two choke transformers (66mm).

 

An analogue meter reads sound output and checks current flow of output vacuum tube. A user can adjust the current flow to an optimal condition by referring an analogue meter.

 

A digital meter measures up to 0.0001V of voltage and checks Hum voltage The voltage is adjusted to the optimal level. Therefore, it is safe even in high-performance speakers. It guarantees clean and dynamic sound that you can never experience in other products.
