I quite like the B5750 tubes, but don't actually need them. I wanted the
B5870s as I wanted spares for my Nixie watch I made. The B5750 tubes are

Hi folks-
I've accumulated a few DT-1704C VFDs over the years. Although I would
rather have Y1938s with their blue tint, I also really like these tubes. I
