OTOMON LAB LS-7 drive 45/2A3/300B compatible 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 45/2A3/300B compatible tube amplifier monoblock 7.5W power Zero NFB (O.U.D.D.C)
This is order made product that adopt new circuit O.U.D.D.C, and the result is really amazing in low frequency.
This is prototype version, if you order the same one, all transformer will be new TANGO(ISO) transformers.
All transformers are vintage ones and it has scraches, dust and rust but function is guranteed.

With Zero NFB, the response frequency is flatted from 30Hz to 25Khz, this is impossible to all amplifier that I made before. At -1db it is from 16Hz to 40K Hz.
The output power is 7W with 300B tube. 6W with 2A3 tube and 3W for 45 tube.
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.
