I can make a pretty good guess as to how the Soviets would have done this (if they ever did) based on the Elektronika 7 clock (Reflector tube factory). A black background with the tubes supported on the top and bottom with flat clamps lined with foam. See the first attached picture (ignore the arrows, they are showing unrelated chassis mounting points). Then mount that assembly behind a glass panel with black paint masking out the rest of the "guts" as seen in the second attached photo. More information on my blog here: https://www.glaver.org/blog/?s=elektronika You will want to use a clear or pale plastic matching the tube spectrum instead of pale green since you're using neon/argon displays instead of VFDs. <https://lh3.googleusercontent.com/-VbRxCf2gLZA/Woz1xY6kgII/AAAAAAAAAEg/MIYMvzjdSWI_XXD9fMPPC0x-uiXtEk5OACLcBGAs/s1600/6F5S8788-s.jpg> <https://lh3.googleusercontent.com/-CSzH3FIWWaM/Woz11pV54MI/AAAAAAAAAEk/rNf5ENBJ8p0K2MzCso4HhvC4Eml_hbBJACLcBGAs/s1600/6F5S8861-s.jpg> -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
