I never read any evidence in datasheets or elsewhere that tells me
multiplexed tubes last shorter than directly driven tubes, despite the
somewhat higher current required for similar brightness. Is this really the
case? What do you base this on? In LED's, this generally evens out, and the

I did a simple study of that issue back in 2002, which is findable in
the early yahoo group archives.
The tubes are 'on' for less time, but the current needs to be somewhat
higher for a similar apparent brightness. The tube life is proportional
to something like i^-3 for higher currents. With

The only 'warning' I've seen is in the Burroughs catalog #616, where a
footnote says Note 1: Due to life considerations only long life nixie
tubes are recommended

It is funny to verify yet again that that one man's trash is another's
treasure...
I was just going to post that the LCD robbed much if not all of this
clock's charm. :)

Judging by the photos on Ebay, which show rather dim digits, I would guess
the tubes are multiplexed at their rated-current, which reduces brightness
vs direct-drive.
I definitely would
Seems silly to me to save a few dollars by multiplexing when the tubes are
so costly. My thoughts exactly!

I was thinking of this as a buy for the tube value alone. Then give those tubes
to Michael Barile who would make me a fantastic Barile/Thomas Nixisat derived
clock or clocks with those tubes.

Hi,
Fatter digits for big tubes would mean (much) higher current, which is
proportional to digit surface. This mean higher power consumption and also
earlier end of the tube because of shorts caused by higher amount of
sputtered metal from cathodes deposited on insulator rings..
but it is worth
