Special amplifier using with both VT-62 and 50 tube. Walnut case with 3mm thick of top cooper plate. It took me 3 years for designing the schematic. Prestage is 12AY7(12AT7), driving tube is 12BH7A.

All transformers were special order made from ISO (TANGO), using hyper orient cut core. Power tranformer core was double bigger than normal power transformer. Wiring is teflon silver plated wire.

This can be used with VT-62, 801A or 50tube, there is switch behind and you can change switch as changing tube.
Vintage 50 tube is considered as the most difficult to use in the world. Grid resistor can allow only 10Kohm, while deep bias make it very difficult to drive.

50 and VT-62 is consider as little 211 tube because its sound is nearly same as 211 but output power is smaller. But the sound of VT-62 and 50 is more musical and beautiful, so if you have high sensitive speaker (higher than 97db) then this is the best matching for your speakers.

This amp can be used with any kind of 50 tube, even vintage RCA UX-250, UX-350, as well as all kind of VT-62, 801 tube.

Specification:

Response frequency : 10Hz ~ 100KHz(-1db)
Distortion(THD): 0.45% 1W
