OTOMON LAB 71A/101D/205D drive 211/845 tube amplifier 20W power/channel (O.U.D.D.C)
OTOMON LAB 71A/101D/205D drive 211/845 tube amplifier 20W power (O.U.D.D.C)
This use 396A as prestage tube, in drive stage you can use 71A/101D or 205D compatible, drive power stage 211/845 tube, generate 20W of power/channel.
If you see this amp is sold out, order made price for the same amplifier is 4500USD
This is order made product that adopt new circuit O.U.D.D.C, and the result is really amazing.

No tubes are included. This amplifier is working in class A, single end mode generate 20W of power for one channel !!!
With Zero NFB, the response frequency is flatted from 25Hz to 25Khz, this is impossible to all amplifier that I made before. At -1db it is from 16Hz to 35K Hz.
The output power is 20W. Almost 211 SE amplifier that I have made before has much distortion after 15W, this one get 20W of power at only 5% of distortion.
The sound as testing in our system perfect. Warm, dark and very detail. 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 ~ 35KHz (-1db) Flatted from 25Hz to 20Khz
Hum level: 0.5mV
THD : 5% 20W
