【Prototype】 OTOMON LAB 71A drive VT-62 tube amplifier monoblock 13W power Zero NFB (O.U.D.D.C)
【Prototype】 OTOMON LAB 71A drive VT-62 tube amplifier monoblock 13W power Zero NFB (O.U.D.D.C)
Input is 100V only.
To keep the analog and musical sound, heater of VT62/801A is AC heater.
This is prototype version, if you see this one was sold out, price for order the same one is 3000USD.
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 is 801A or VT-62, can be changed to use with 50' tube.

No tubes are included. You can not order 117V or 230V, only 100V. This amplifier is working in class A, output power is 13W. Zero NFB !!!
With Zero NFB, the response frequency is flatted from 25Hz to 35Khz, At -3db it is from 16Hz to 45K Hz.
The output power is 13W/channel which is impossible for VT62 PP tube, which is normally generate about 8-9W at THD 5%.
Specification:
Response frequency : 16Hz~45KHz
Hum level: 0.3mV
THD: 13W @5%
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.
