OTOMON LAB VT-62/VT-25/10Y drive PX-4/PX-25 compatible tube amplifier 8W power Zero NFB (O.U.D.D.C)
Technical data is just an improve that item was tested carefully before sending to customer. While our products consistently achieve good to excellent technical figures compared to commercial alternatives, those numbers serve only to confirm that the design contains no engineering errors.
We could, in most cases, apply active techniques to make the specifications look even more impressive — but if doing so strips away originality or musical character, we will not do it. Our aim is to build equipment that sounds beautiful, not equipment that measures beautifully.
At OTOMON, music is judged by the ear and no instrument can replicate the human 's ear.

OTOMON LAB VT-62/VT-25/10Y drive PX-4/PX-25 compatible tube amplifier 8W power Zero NFB (O.U.D.D.C)
This amp was order to use with EML PX-25 tube, you can order to use with PX-4 compatible.
This use 396A as prestage tube and VT-62(VT-25/10Y) as driver tube to drive PX-25 tube, rectifier tube is 5U4, GZ-34, GZ-37 vv..v
This is order made product that adopt new circuit O.U.D.D.C, and the result is really amazing. Generally PX-25 tube gernerate 5-6W of power at THD 5%, with this schematic it can reach to 8.5W of power at THD 5%

With Zero NFB, the response frequency is flatted from 28Hz to 25Khz, this is impossible to all amplifier that I made before. At -3db it is from 16Hz to 40K Hz.
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 (-3db)
Hum level: 0.3mV
THD : 5% 8.5W(with driver tube VT-62)
Tubes are not included.
