OTOMON LAB VT-62/VT-25/10Y drive VT-62/50' tube amplifier 8W power Zero NFB (O.U.D.D.C)
OTOMON LAB VT-62/VT-25/10Y drive VT-62/50' tube amplifier 8W power Zero NFB (O.U.D.D.C)
50' tube is one of the best vintage tube , generally, it has 3-5W of power but with O.U.D.D.C schematic, it can reach to 8W of power, no NFB
This use 396A as prestage tube and VT-62(VT-25/10Y) as driver tube to drive 50' or VT62 tube, rectifier tube is 83' tube or 5Z3
This is order made product that adopt new circuit O.U.D.D.C, and the result is really amazing.

All parts are new ones. No tubes are included. This amplifier is working in class A, single end mode generate 8W of power for one channel. Zero NFB !!!
With Zero NFB, the response frequency is flatted from 28Hz to 30Khz, this is impossible to all amplifier that I made before. At -1db it is from 16Hz to 40K Hz.
The output power is 8W. Almost 50 SE amplifier that I have made before has much distortion after 3W, this one get 8W of power at only 5% of distortion.
The sound as testing in our system is really good. The biggest characteristic of O.U.D.D.C is that it bring a quite difference bass sound. Deep, open sound stage and detail.
There is option that allow very little NFB (-3db ), if you dont like NFB, you can choose Zero NFB by changing the switch.
Specification (Zero NFB)
Response frequency : 20Hz ~ 40KHz (-3db) Flatted from 28Hz to 30Khz
Hum level: 0.3mV
THD : 5% 8W
