querry about B-9012 pixie tubes

[Bogdan Paduraru]

Hello all, 
I have some B-9012 pixies and I want to build a 6 digit clock using them .
Does anyone build anything with them ? what is their life span ?
Please share your experiences with these tubes

Thank you

Have you searched this forum?

I know that at least one person has built a clock with these, can't remember who right now but I think it is one of the members of this forum.

Usually I search before asking questions 

Although I didn't read all replies on all conversations that had mentioned "9012" in them, I did not saw anything that leads to a final product 

Will recheck everything next days

The data sheets I’ve seen featuring the 9012 suggest it should last at least as long as standard long-life Burroughs tubes, though I’d bet they’ll last twice that or more given the minuscule cathodes. It’s a shame they’re as rare as they are, I’d love to see more clocks feature them.
