Where can I buy...
 

a back-up crt With the # 370AUB22 ..? A search of the net turned up none in stock, and last price was 240$ for one. It's a 13" Blackstripe tube from the mid 70s.
I'd like to purchase a backup since one of my favorite solid state tv's uses it. Thanks (also, if anyone knows a tube that crosses with it for substitution, let me know please !

What does this tube fit? Model and photo will help.

It might be much easier to buy a spare TV with good CRT, rather than hope to find that CRT just sitting around.

I may have the whole set. Ill look. I thought those never failed though

Well i'm not sure they cannot fail, all tubes can...but yes mine is still strong. Alls I'm saying is that it'd be nice to have a spare. If they're remotely available.
it fits a number of Japanese sets from the 70s including Sanyo, Toshiba, Teknika(sp?), Midland etc. I have a cross reference book that doesn't list any other number for it...just that its a mid seventies Japanese inline color. Which I knew...
