There are a total of 3 tubes: 2 of 10EW7 and 1 of 21LU8. The manufacturer is unknown for one of the 10EW7 tubes, as the markings have faded. The other 10EW7 and the 21LU8 are SANYO. 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 device. However, I have confirmed heater continuity. The SANYO 10EW7 has a side getter. The tubes come with the original box, but it is quite worn. The other two tubes do not have boxes. I plan to ship via Takkyubin Compact, but may change to Yu-Yu (anonymous shipping).
