Preidcta Holiday CRT testing

[madlabs]

Thanks for the replies!

I don't see any tag or markings on the tube itself. Attached to the shroud is a tag that reads: C 7100199 Part Number 319-2100. It is pasted over another sticker. I'm guessing it is a shroud number and has nothing to do with the tube.

Can the B&K 465 do the 2v and 6v filament? I know you said all voltages but I just want to be sure. I looked for a manual for it but couldn't turn one up. Since I see it recommended here and other places not to use these testers for rejuvenation, it seems that it can be done with the stuff most folks would have laying around, like in this link:

I'd use a 6.3VAC filament transformer and use a variac to get the voltage right and use a variable DC power supply for the 100V. Does this seem reasonable? Any tips or words of wisdom or links for rejuvenating?

Just how hard is it to find a replacement CRT for this thing? I could live with one with a too long neck if need be. Hopefully this one is workable but if not how far up the proverbial creek without a motivational device am I?

No one has mentioned the idea of replacing power supply caps to prevent major damage and see if the CRT lights up? Is this because only an idiot would do that? Or because there are just too many things that can prevent raster that it won't mean much as a CRT test?

Thanks for answering my noob questions, doubtless for the nth time. I am reading all the old posts and doing as much RTFM as I can.
