OTOMON LAB 71A drive VT-62/801A tube amplifier monoblock 7.5W 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 71A drive VT-62/801A tube amplifier monoblock 7.5W power Zero NFB (O.U.D.D.C)
This absolutely the best VT-62 tube amp that I have ever made. The chassis is Sound Exprorer SL-770, impossible to get the same chassis so if you order, the chassis will be difference a little.
This is order made product that adopt new circuit O.U.D.D.C, and the result is really amazing in low frequency.
Prestage tube is 396A, drive tube is 71A, output power tube can be used with VT-62 or 801A

All parts are new ones. No tubes are included. This amplifier is working in class A, single end mode generate 8W of power for one channel. Zero NFB !!!
With Zero NFB, the response frequency is flatted from 30Hz 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 7.5W (No NFB). Almost VT-62SE amplifier that I have made before has much distortion after 4W, this one get 7.5W 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.
Specification (Zero NFB)
Response frequency : 16Hz ~ 40KHz (-1db) Flatted from 30Hz to 30Khz
Hum level: 0.2mV
THD : 5% 7.5W
