Jeff, Of the 30 or so tubes I have at home, only 4 have the post. (I will check more when I get to work tomorrow.) What I did notice is that not only did all 4 have the mica spacer at the top, but that all the other regular tubes have the spacer with the hole for the post pre-punched out. Also, the tubes with the post stand about 4mm taller to account for the additional space needed for the post height. Michail

I'll dig them out and post a couple photos. Jeff -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
