This listing is for a vintage 12AT7 ECC 81 tube. The tube has been tested for short, leaks, and there is no quality issues. The tube tested great and the boxes in great condition.

This is one of the rare tubes that has a double halo, getter and gray plates. These are probably the most sought RCA tubes of this type

Happy hunting
