Hello Charles, It is there. 0Z4, 0Z4G, along with 0Z4A.This appears to
be an oddity. As far as the JEDEC files in the TCA 'data cache' go the
0Z4G is listed in the INDEX under "Main type", and references the same
exact release number as the plain 0Z4 of #49. Upon opening up release
#49 there is

Upon further investigation in TCA's data cache, I find the following,
0Z4 first registered by Raytheon on Oct 24th 1935 with a metal shell
which tapered down in size as it got closer to the top of the metal
shell, an 0Z4A first registered by Raytheon on Oct 15th 1956, with the

By the way Grahame, FYI, they were used extensively, (and only???) as
the cold cathode full wave rectifiers, in vibrator type power supplies,
for automobile radios. I know of no other use, but might be interesting
to see what others here may say on that. Ira.

Right, I've only seen the metal can version - that was a few years ago
as well. G

0Z4 is metal.
0Z4G is glass.
0Z4GT is glass, but tubular, not curvaceous.

There were TWO versions, metal can with octal base, which by far and
away was the majority of them, and also a GLASS version, 0Z4G. Ira.

May be an open mercury vapor rectifier, like a 866 (not an 866A !) does the

Don't know what spectrum OSAGE rectifiers radiate. anyhow they have no

If that were the cause, then I'd recommend a vigorous shake to remix the
gases :) Seriously though, the contents of your tube are 98%+ neon, with
the balance being argon and possibly a trace of mercury vapour. No air of
any description in there, else it wouldn't glow at all under the voltage

Perhaps I should use something less vivacious, yes. At first I just
left the strip light over the workshop bench on (40W at 1.5m) and that
was fine as well. I used the pond lamp as I had a spare to hand - it
needs to go out to the pond filter box now it is spring. Perhaps a

Many thanks for the advice,
I raised the voltage to 180v and the tube seemed to behave more like I
would expect and at 190v was ok. However the other tubes in the multiplex
developed a hazy pink glow so I quickly turned the voltage back down. I can
only conclude that the tube is on its last l
