@th That reminds me of the Nixie clock my friend made, except he accidentally bought tubes that didn't have any numbers! https://hackaday.com/2015/07/14/unusual-nixie-tubes-lead-to-unique-clock/

@th Even back when that was new, replacement tubes with the non-numeric cathodes must have been a major pain to source.

@th I had the DC-only version of this meter! Nice to see another up and running, and with a more complete option set :P
