I have handled a lot of 5870 tubes, making Nixie watches. About 4,000 so
far.
I have noticed that there are different diameters of lead wires on these
tubes. (The lead wires are cast into the glass header, and the cathodes
are spot-welded to them.)
The thickest leads are 0.40 mm diameter, while the typical ones are 0.35
or 0.38mm. I just encountered one today with 0.29mm leads.
quick look for a data sheet shows they are specified as 0.014 to 0.017
Typical diameter. that gives .35 to .43 in mm if I did the conversion
right.
