The single-ended amp has a very strong sense of music, and the output internal resistance is lower than other circuits,  can drive headphones in the range of 32-600 ohms. The sense of dry control and extension are better than Transistor machines. It is recommended that 100-600 ohm headphones have the best effect, and the air and details are really first-class.



Because both the filament and high voltage in the setup use DC voltage stabilization, the signal-to-noise ratio is extremely high, and it is quieter than ordinary Transistor machines.

This board uses very good materials,  DALE resistors, German Red Weimar coupling, Philips filter capacitors, etc.,it with the ALPS volume Potentiometer.

It is using 1pcs 6N5P  and 1pcs 6N11.   the 6N11 can updates with ECC88/6922. the 6N5P can use 6H5C.


Works voltage: AC115V  or 230V  for choose
External dimensions:   width 202mm    height 80mm      depth 282mm
Package weight: about 5kg/unit


Note:   Default price are not include the Audio input RCA cable and AC power cable!
