I am the second owner of this device. Bought it from original owner in 2019 and has been my daily driver ever since. The device is in great working condition and overall is well-maintained. Will come with power and USB cable. As shown last couple pictures: 1) Minor scratch on bottom surface not visible during use 2) Barely visible hairline scratches on volume knob - really have to play around with the lighting and angle to catch it Note: requires 1/4” end to connect to DAC/AMP

UFL to N-Female Bulkhead 12 inch CA178-NFB-UFL-12 Pack of 4

CA178-NFB-UFL-8UHL to N-Female-Bulkhead8 inch tail.See pictures for more details.(Pack of 6)

This is order made product that adopt new circuit O.U.D.D.C, and the result is really amazing. All parts are new ones. No tubes are included. This amplifier is working in class A, single end mode generate 7W of power for one channel. Zero NFB !!! This one was made to compare with all VT62 tube amp that I have ever made. The result that was calculated via Technical Tester and Hearing via speaker improved that the O.U.D.D.C (Detail in OTOMON website) is bringing the best sound ever for the amp. 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 7W. Almost VT62 SE amplifier that I have made before has much distortion after 4W, this one get 7W 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. There is option that allow very little NFB (-3db ), if you dont like NFB, you can choose Zero NFB by changing the switch. Specification (Zero NFB) Response frequency : 10Hz ~ 60KHz (-1db) Flatted from 20Hz to 40Khz Hum level: 0.2mV THD : 5% 7W /////////////////////////////// NOTE: 1.
