Martin - Have you tried measuring the resistance of the pin's corrosion ?
Scrape-away the corrosion at one and of the pin, and try measuring at the
opposite end with minimum pressure. Might need an analog meter, or at least
disable autoranging on a DMM.
I've only seen corrosion on IN-18's and i
Could you use an old 'scope ? Or would it be too big ?

I use a 3M diamond abrasive plastic film which you can get in finess down to 1 micron. I use a 10 Micron one for very fine gentle sanding of things like nixie pins. It is slow but effective. Coarser versions would work faster.

Hey all,
I am looking for a 5"-6" monochrome CRT, preferable green or amber, with
composite video input. If anybody has one for sale, please let me know!

You can find the IV-25 on Gstube too: http://www.gstube.com/data/1694/
Their general datasheet page is here: http://www.gstube.com/data/

I can't find a datasheet for IV-26 so I don't know what the difference
between the IV-25 and IV-26 is.
Does anyone know?
I have around 700 IV-25 tubes here and they all have non-clipped circular
dots.

Hi everybody,
Many thx for your help. Sorry for late reply, I don't know why, my email
software doesn't show up your replies.
w30, my son bought it 2 years ago on ebay, I had to investigate to identify
the model. Obviously I was wrong.
I'm sorry I bought a counterfeit model. Maybe it just does
