[Protype] OTOMON LAB VT-62(VT-25) drive 50'/VT-62/VT-25/10Y tube amplifier monoblock 9W power Zero NFB (O.U.D.D.C)
OTOMON LAB VT-62 drive 50'/VT-62/VT-25/10Y tube amplifier monoblock 9W power Zero NFB (O.U.D.D.C)
This absolutely the best 50' tube amp that I have ever made. This is prototype version, if you see this one was sold out, price for order the same one is 3500USD.
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 VT-62(VT-25), output power tube can be used with 50 tube or VT-62 or 10Y,VT-25

All parts are new ones. No tubes are included. You can order 117V or 230V. This amplifier is working in class A, single end mode generate 9W of power for one channel with 50' tube. Zero NFB !!!
With Zero NFB, the response frequency is flatted from 30Hz to 35Khz, this is impossible to all amplifier that I made before. At -1db it is from 16Hz to 40K Hz.
The output power is 9W with 50 tube (No NFB). Generally 50' tube always has max power 5-6W, this one get 9W 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.
Specification (Zero NFB)
Response frequency : 16Hz ~ 40KHz (-1db) Flatted from 30Hz to 30Khz
Hum level: 0.3mV
THD : 5% 9W
