FX-AUDIO TUBE-P01J Black This is a tuned model. Purchased new from NFJ in 2020. I enjoyed the sound of the vacuum tubes, which is different from transistor amplifiers, and used it comfortably for about two weeks. However, I upgraded to another vacuum tube amplifier, so I stored it without using it. It is a beautiful item with almost no signs of use. During the recent operation check, the pleasant overtones and clear sound quality were outstanding. Although it may depend on the compatibility with other devices, the high frequencies are not harsh, and the low frequencies have a relaxed, analog-like richness. It is not tiring to listen to, and I think it is a quality that exceeds the price as an introduction to vacuum tube amplifiers. The included two 6J1 vacuum tubes and two 6P1 vacuum tubes are matched pairs that can stabilize the operation of the vacuum tubes and adjust the sound quality. In addition, a vacuum tube protection cage and an AC adapter are included. Furthermore, this time, I will include "four 6*1NEB tubes compatible with 6J1 vacuum tubes" and "Petit Susie V3.0", which removes noise components from the power supply by connecting it between the AC adapter and the vacuum tube amplifier, so I think it is a great deal. Please check the specifications of the product itself on the web, etc. It will be delivered as is. Although there is almost no feeling of use, please refrain from purchasing if you are concerned about it being a used item. Also, please understand that no claims or returns are accepted. * Immediate purchase is possible. #FX-AUDIO- #TUBE-P01J #Integrated Amplifier #Vacuum Tube Amplifier #Amplifier
