I have just been pointed here because of a discussion about the 6922EH tube on diyaudio.com. Someone posted a link to your pictures of a broken 6922EH, the one with the getter fixed at both ends. I have a number of 6922EH tubes dated 2011 and they have the getter fixed at one end only. Your pictures look more the the JJ E88CC tubes I also have. This is puzzling.
Cheers
