[NJARC] Museum Needs CRT

[David Sica]

I'm pretty sure I have a couple of 3RP1s lying around.   As a
"don't-force-it-get-a-bigger-hammer" substitute for the Pilot TV CRT, I
pick them up whenever I run across one inexpensively.

The trick, as usual, will be to actually locate it in the endless piles of
radio merriment in the basement.

Have you considered rejuvenating the existing tube or wiring in a
brightener?  There's a decent chance that one or the other of those tricks
will help, possibly for quite a while.

I expect to be at InfoAge on Sunday afternoon; I'll let you know if I find
one and if I do, I'll leave it at the museum for you.
