I did not realize there were different types of DT1704 tubes. I have a single Tung-Sol DT1704 still in its original RadioShack "Archer" packaging that I bought around 1975. I had already built a single digit Nixie counter following a supplied schematic using 7490, 7475 and 7441 TTL chips. I wanted to build a similar device using a 7447 in place of the 7441 since the decade counter and latch were independent of the display. But those parts were expensive for a young teen and I was only able to afford to build the Nixie counter because I made it a school science project and my parents gave me the additional money I needed after I paid out my newspaper money. Might be something for me to do when I retire in a few years. I have a been buying all kinds of small electronic gadgets and parts from AliExpress for ages with plans to someday make something interesting.
