One 7DJ8 tube. The manufacturer is Toshiba, and it comes with the original box. As I do not have any equipment that uses this vacuum tube at the time of listing, I have not been able to confirm its operation in a real device at the time of listing, but I have confirmed heater continuity. The base of the pins is also clean, so I believe it is unused, or close to it. I will send it via Nekopos (a Japanese delivery service).
