Maintained by the manufacturer in 2024! There is a repair mark on the left side, but the appearance is good! It is a vacuum tube amplifier that allows you to enjoy the “fresh and glossy sound” typical of Uesugi. It is a specification where you can feel the attention to detail, such as using a transformer jointly developed with Tamura Seisakushita and sorting tubes made by Matsushita. The wiring done by hand by craftsmen is also a highlight (Daiki Goto)
Maintenance information: 2024.8.6 manufacturer maintained (replace 2 12AX7. The hot side of the pin jack was loose, so it was fixed. Using a highly rigid shielded cable may damage this unit's pin jack. (Note that if you push this unit deep into a rack or the like without the pin plug inserted all the way, the back will be pressed against it and the pin jack contacts will twist, causing poor contact.)
