But, there's his nixie (made by David Forbes) watch in it.

I've just looked through some displays, the only difference I can see
is the two IV-17s here (8909 and 9305) have a small dimple in the
centre of the shadowmask.
I also have a box of IV-4s dated 0286 which are printed using white
ink.
The 1000 hours lifetime is hopefully a misprint, there shouldn

anyone else except me.

I've just had a look at all of the types of IV4 and IV17 tubes in my
collection to try to establish what, if any, are the main differences.
Due to the high res images producing a large file size I couldn't
upload the document here, so I've posted it on Mediafire

It's a general characteristic of gaseous discharges. As you pull more current

On a household circuit, the neutral is generally cross connected to
ground. In an industrial setting, one can get 110 volts from connecting

As long as we are on the subject of simple power supplies
for first-time nixie clock experiments, I would like
to toss in my two-cent's worth.
For the 5 volt supply needed for the logic, I usually
use a 7805 regulator. Those work very well and put out
1 amp. They are easy to use. They will take
