Would a JVC CPJ370BVBKIUST tube work in a WG 13k48xx chassis? Raised in the glass on the tube is an "N" and "14", so I'm thinking I'm SOL as that would indicate a 14" tube and I need a 13", right? Would it have been ok otherwise? Probably too new of a tube, but at least the neck board from the 4800 fits the back of the tube.

Hmmm...even if it's wrong, something is wanting me to connect it all up and plug it in and see what happens anyhow. I might have to record and youtube that.
 
Other 370's that I've seen have been good 13" replacements. You'll have to do a diagonal measurement of the viewable area to see exactly which size it is.

The problem is that the 13" versions of different chassis' don't always have the same pinout as the 19". For example,the 19" G07 is a CR-23, but the 13" G07 is a CR-28.

So, you have to check to see what tube your 13K48xx is using, check to see what pinout it has, then whether it uses the same pinout as the donor tube. The tube you mentioned (370BVBK1UST) has a CR-31 pinout...
