I had no problems with tube variations but I did make up a test jig for development of the interface so I was sure it would work once I actually built it. Mine uses a 400 volt anode supply, an Atmel Mega 32 as the processor and has a GPS receiver and PIR detector as well as a little nixie to display the number of sats in view. It's still going strong on the window sill of my study. I had a lot of fun doing this and of course, the nerdy technology is simply wonderful. However once it was finished it was rather unsatisfying. Unlike other clocks you can't just glance at it and know the time. We are (or at least I am) so used to either clock face or digital displays that it's an effort to get used to anything different. It was a lesson for me about the limitations of unusual display formats for such a familiar task. In fact since I built that clock I had a chat with a broadcast studio engineer who told me of the difficulties many announcers in radio studios have reading certain clock displays. He said that he now installs both clock face and digital clocks where announcers can see them to make sure they can read the time. In my day job in medicine the clock drawing test is a well known and very sensitive indicator of cognitive impairment. All you need to do is ask the subject to draw a clock face with the hands set to a certain time. It's amazing to watch even mildly depressed or demented patients attempting it.
