The single-ended amp has a very strong sense of music, and the output internal resistance is lower than other circuits, and it can drive headphones in the range of 32-600 ohms. The sense of dry control and extension are better than stone machines. It is recommended that the effect of headphones under 100-600 ohms is the most ideal, and the air and details are really first-class
This is a kit, need to be welded, no debugging, kit does not contain potentiometer and tube, need to be photographed separately
Option 1, kit(Without tube and potentiometer)
Option 2, one for 6N11 and one for 6N5P
Option 3, finished board with potentiometer, without tube
Because the filament and high voltage in the setting are both DC stabilized, the signal-to-noise ratio is extremely high, and it is quieter than ordinary stone machines
The kit uses very good materials, Philips resistors, German ERO coupling, Philips filter capacitors, etc.
PCB size: 143mmX 108mm
Upgrade plan: The upgrade plan is very simple, the core is 2 tubes, 6N11 can be upgraded to imported ECC88 , 6N5P can be upgraded to sound poison
