Every now and then, I take a peek at ETF's site to see what they have on their classified list of CRTs for curiosity's sake, I just find it interesting, but for some time now, there has been 2 on the color list that I can't seem to work out WHAT the hell they are... I mean, if a google search comes up with no hits, the must be REALLLY oddball tubes or something, so rather than bug Steve with an e-mail for mere curiosity, I thought I would ask here to see in anyone could work out what they were.
They are listed as.
21CGP22 used
21VGB22 used
