Even though the B5025 has the same pinout as the ZM1030, the electrical
characteristics are bit different. The ZM1030 has the same levels as normal
(non-biquinary) nixies. Strike at ~170V, and maintain ~130V. The B5025
strikes ~130 to 150V, and maintains ~100V. Also the ZM1030 is a mercury

Hello Jens,
pretty sophisticaed way of leak detection ;-)
what do You think by the "insufficient greasing on my needle valve"? The
rubber o-ring used to connect the valve to the system was not greased
properly? Or something else?

I am not sure if the picture is visible, so it is attached..

Hello Michael,
10E-6 torr is not necessary. For testing purposes is 10-2 torr enough,
because then the tube is filled to somewhere around 30 torr what is much
higher pressure.. The initial pressure is not so critical in nixie tubes,
but influeces the total lifetime of the tube.. However it would
Hi Dalibor,
what do You think by the "insufficient greasing on my needle valve"?
The rubber o-ring used to connect the valve to the system was not
greased properly?
yes, there was some fibre or something hair-like that caused a small leak.
I think that the valve stem is not fully pressed to
Hi Michael,
yes, I will document everything on my website. In fact, most of it is
already done, but right now I am writing the vacuum system part and I
want to document all the steps that I did until now. And now it is far
from perfect. So I will show all different setups and number them. My
Hi Bryan ,
Ok took some photos so you can get an idea of what they look like. The
series resistors are 1/8 watt 100 ohms and the supply voltage is 5 volts .
Unfortunately Google says they're too big to post .I'll send them to you
personally . Your e-mail address is masked so I can't see the
