Four 6EJ7 tubes. The type number silk screening is readable on all four tubes, but the manufacturer silk screening has disappeared on all four. The font of the type number silk screening is the same on all four tubes, so I believe they are from the same manufacturer. 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. The base pins are clean on all four tubes, so I believe they are unused, or in a condition close to unused. There is no box. I will ship via Nekopos.
