The NSN is 5865-01-289-9651EW and it's made by Loral Electronic Systems.
OK. I know I don't have one, but I can put it on my watch list.
I did verify that the tube is indeed a 4" tube.
The 4AP10 CRT number that
you mentioned I found online for $85.
The problem is that the 4AP10 is the one you simply can't use. P10 is a
bizarre dark phosphor, with a very VERY long persistance.
If you have access to the documentation on the unit
I've got, I would
_love_ to get the tube specs and pinouts.
I'll post a query on the TCA list. Tube geeks, basically...
It also has a set of symbols like this: [O] burned
into the 12 o'clock
position. Any idea what that's for?
My guess is "no threat".
