Apollo Numitron Tube Clock
Apollo Numitron Tube Clock
2020
Like the high voltage Nixie tubes, I also have a love affair with low voltage incandescent display tubes, or Numitron tubes. These types of tubes were also used as numeric displays back in the 60s through the 80s, and now are available in surplus. I designed and fabricated a number of clock designs from 2010 to the present, and continue to refine clock designs based on various tube types.
Probably my favorite numitron tube of all is the IEE Apollo Numitron DA2010 and DA2000. These were later duplicated by RCA and can be found in DR2000 and DR2010 model numbers.
