Even more info!

Same goes for IN-4, there is specified current for half-wave rectified 50Hz
voltage. It is 1,5mA for IN-4.
Aaaand we've got it! (As long as we assume that we can extrapolate the
half-wave rectified average current to average current
If we assume that IN-8 and IN-8-2 are electrically the same, then I've
digged some info. For pulsed operation from 50Hz (one half rectifying?
"one-half ??? without filter, sounds like just a diode) the average current
should be 1mA. I think that we can extrapolate this data to just "average

Thanks everyone for the responses. I'm working on the IN-8 clock at the
moment. I set the voltage to 200V. When i had the 22k resistors in, my
current on one tube was 0.45mA, so multiplying that by six I only got
2.7mA. I put a 10k in and am getting about 0.88mA which gives me 5.28mA,
which
Thanks for the warning. Generally, I leave everything plugged-in 'forever',
which is probably why I havn't had problems yet.

Mostly unrelated, but... I've had bad experiences with devices very similar

1 - You can safely assume that "Pulse Voltage" is the one supplied by your
Power Supply. It is higher than the one needed for non-multiplexed
operation to guarantee a faster strike.
2 - Both modes A and B are safe from an operational stand
As will I, I have some nixies, numitrons, VFDs, and some rare early HP 7
segment displays available as well.
I am seeking a Pandicon and IN-17s.

Thanks!
I have the special IN-16, but I never looked close enough to notice that it
really is a horizontal mesh nixie!
The inverted types are very nice! I'll have to check the English eBay more
often.

Excellent idea!
I'll put together a trade list as well.

To be honest, I don't understand the timing values from datasheets either.
I would just assume that if the DC current of IN-4 is 2,5-3mA, and IN-8 -
2,5-3,5mA, then in 6 digit multiplex 5mA in pulse on each of them wouldn't
hurt them at all - that is still 1/3 of nominal power dissipation of a D
