OTOMON LAB 2A3 drive 211 tube amplifier 18W power Zero NFB (O.U.D.D.C)
OTOMON LAB 2A3 drive 211 tube amplifier 18W power Zero NFB (O.U.D.D.C)
This model is closed, you can order the one which is same schematic but not same design.
This use 396A as prestage tube and 2A3 as driver tube to drive 211 tube, generate 18W of power/channel.
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 18W of power for one channel. Zero NFB !!!
With Zero NFB, the response frequency is flatted from 25Hz to 20Khz, this is impossible to all amplifier that I made before. At -1db it is from 16Hz to 30K Hz.
The output power is 18W. 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: 0.8mV
THD : 5% 18W
