OTOMON LAB 211 drive 211/845 tube amplifier 20W power (O.U.D.D.C) x 2 monoblocks
OTOMON LAB 211 drive 211/845 tube amplifier 20W power (O.U.D.D.C) x 2 monoblocks
This use 717A x 2 as prestage tube and 211 as driver tube to drive 211 tube, generate 18-20W of power/channel.
Output transformer uses speacial order made transformer, using super core, transformer weight 9kg each, size is W15xD135xH180mm, very big ones.
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. Output tube can be used both 211 and 845
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 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 ~ 45KHz (-3db) Hum level: 0.5mV
THD : 5% 20W(with 845 tube)
