The product is a rare pair of Western Electric 421A vacuum tubes with double D's top getters. These tubes are an earlier production where they used the double “D” getters on top. These tubes date codes match and they tested balanced and matched to each other.

They have date code of 1967. The tube was tested on TV-/U at around 62/40 min good (100%=60). There are two available on request but price is for ONE tube. I found it on the attic shelf from my grandfather’s collection.
