Last week I noticed another 1846 for sale on the 'bay. It had
a good center of the getters, clerly visible, so I bought it. It arrived yesterday and today I tried it. It works identically to my other semi-working one. It runs for about 15 to 30 minutes and then the bias need raising and it loses the picture. Turning off 10 minutes and the picture is back Questions for those, especially the Aussie guy, who have gotten one to work indefinitely: is there a brown rim around the shiny getters or are they all shiny? Have you experience of a tube acting like mine? Do you think that maybe it could be an electrical fault since the two tubes work or don't work identically? I have a similar appearing third tube that does not produce any picture at all.
