This tube has been in my collection for twenty years, as a very clean example of one of the best of Western Electric's great tubes. The test when I got it rated both plates as good. And the general condition suggests very light use if any. The pictures show the getter flashings are perfect. I get continuity in the filament. No shorts. Date coded 59-26.
