Re: Availability of TV valves for Nixie Clock.
I know nothing about these things, but maybe these can help.
You probably all know of the 74141 used to drive the ZM1000 nixie in Grundig 6010 and 6011 colour TVs.
Later of course they went to 7 segment LEDs with the appropriate chips to drive them. This came to mind when I was working on my Advance frequency counter. That used 7 segment "nixie" tubes with a DS8880 driver chip. Not sure if that would be any use to you.
