Thanks Mike - you have mail. > One little curiosity, look at this photo at Dieter's page: > > [snip] > > Makes you wonder if there were 3rd party vendors > that supplied the glass. The Z303C and GC10B envelopes are generally pretty similar too (wih some slight exceptions for early models). I'm sure there were suppliers of subassemblies for things that were common across valves, such as bases with the metal pins already in place. Keith Thrower's fascinating history of the EF50 (sorry, no neon) hints that the manufacturers of valves used modules which might have been made separately. http://www.r-type.org/static/ef50.htm Cheers, Jon. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
