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 45/2A3 PP tube amplifier 20W power monoblockx2 Zero NFB (O.U.D.D.C)

This is absolutely the best 2A3PP amplifier that I have ever made, using O.U.D.D.C schematic

This is order made product that adopt new circuit O.U.D.D.C, and the result is as usual, really amazing.
All parts are vintage ones. This is order made amplifier, so if you order the same one all transformer are new ISO (Tango) transformers. No tubes are included. This amplifier is working in class A, double pushpull mode generate 20W of power for one channel. Zero NFB !!!

With Zero NFB, the response frequency is flatted from 20Hz to 40Khz, this is impossible to all amplifier that I made before. At -1db it is from 10Hz to 60K Hz.

The output power is 20W. Almost 2A3PP tube amp generate 10-12W per channel.

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 : 10Hz ~ 60KHz (-1db) Flatted from 20Hz to 40Khz
Hum level: 0.2mV
THD : 5% 18W
