I built a bunch of multiplexed clocks in 2001-4 using the 74141 chip, which the Russian chip is a copy of. I used various Burroughs and Philips tubes. I found that the multiplexing worked well on a PC board, with 100 microseconds to a millisecond of dead time before changing the binary value at the 74141 inputs. This time is needed to allow the tube to stop ionizing, so that the next number's ghost won't appear on that tube.
