OTOMON LAB VT-62 drive 300B tube amplifier 10W power Zero NFB (O.U.D.D.C)
OTOMON LAB 71A/101D drive 300B/PX4 compatible tube amplifier 10W power Zero NFB (O.U.D.D.C)
This use 396A as prestage tube and VT-62 as driver tube to drive 300B tube, generate 10W of power.
This is order made product that adopt new circuit O.U.D.D.C, and the result is really amazing.
This is prototype product, if you order all transformer will be new TANGO (ISO)

All parts are new ones. No tubes are included. This amplifier is working in class A, single end mode generate 10W of power for one channel. Zero NFB !!!
With Zero NFB, the response frequency is flatted from 25Hz 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 10W. Almost 300B SE amplifier that I have made before has much distortion after 6W, this one get 10W 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 : 16Hz ~ 40KHz (-1db) Flatted from 25Hz to 30Khz
Hum level: 0.2mV
THD : 5% 10W
