Well, the higher the anode voltage you use, the less important are the
equalizing resistors.
For the CD47 250V are recommended at the datasheet, and this voltage
equalizes the cathode current automtically.

Subject: [neonixie-l] Cathode equalizing resistors?
Hi,
I stumbled across "cathode equalizing resistors" in the GR10G
datasheet (http://www.jb-electronics.de/html/elektronik/nixies/
n_gr10g.htm?lang=en). They say 8k2 and 4k7 resistors are required to
account for the smaller size of "1" and "7".
Have you seen equalizing resistors mentioned for other tubes than the
GR10G?
Although I have never read about those in other datasheets or web
sites about nixies, to me equalizing resistors sound like a very good
idea. I guess they will increase tube live and I think I will add them
in case I ever build driver boards for my CD47s or Z5680Ms.
Regards
Markus
