Four 6BZ6 tubes. The manufacturer's silk screen is MOTOROLA. However, there is also a "MADE IN JAPAN" marking (photo 4). The typeface of the model number silk screen is characteristic of Toshiba, so it may be a Toshiba OEM. I do not have any equipment to use these vacuum tubes at the time of listing, so I have not been able to confirm their operation in a real device at the time of listing, but I have confirmed heater continuity. There is no box. I will ship via Nekopos (a Japanese delivery service). The base of the pins is also clean, so I believe they are unused, or close to it.
