OTOMON LAB 300B drive 300B tube amplifier SE Zero NFB 12W/channel
OTOMON LAB 300B drive 300B tube amplifier SE Zero NFB 12W/channel (O.U.D.D.C)
Input voltage can be ordered 117V or 230V. All new tubes are included.
Rectifier tube is 5U4G(GZ-34, 5R4GW) or 83, 5Z3 vvv..
This amplifier use DHT 300B tube driver 300B tube with O.U.D.D.C. Prestage tube is 717A, you can order to use another tube.
Sound is very sweet and rich, very beautiful and clear sound.
Generally, 300B tube gerenrate 7-8W(THD 5%) of power but with this special circus, amplifier reach 12W at 5% THD.
This is product adopted new circuit O.U.D.D.C, and the result is as usual, really amazing.

With Zero NFB, the response frequency is flatted from 30Hz to 25Khz, this is impossible to all amplifier that using another schematic. At -1db it is from 20Hz to 35K Hz.
The sound as testing in our system is really special, very musical and sweet. 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 : 20Hz ~ 35KHz (-1db)
Hum level: 0.3mV
THD : 5% 12W
