Googling "repairing vacuum tube bases glue" will show a few different methods in repairing a vacuum tube when the glass has come loose from the base. Which method you should use depends on what outcome you are looking for, like original if you want it to be authentic looking, or a proper repair taking into account glass and base material expansion when heated (Nixie Tubes get a little bit hot and especially these bigger tubes consume some power).
There are even some slits cut in these sockets which have been described as expansion slits in some datasheets - so maybe these tubes are only glued in one or two places on only a few of the portions where the slits are, I haven't really checked, but you can have a good look before trying any repairs so you get it right. You could also try checking with people at the TCA (Tube collectors Association) if they know the proper way for these Nixies to be re-glued. /Martin On Saturday 22 June 2024 at 19:49:28 UTC+2 Mac Doktor wrote: > > On Jun 19, 2024, at 1:02 PM, <theold...@gmail.com> <theold...@gmail.com> > wrote: > > *Have used regular super glue on several radio tubes with loose bases.
