I've been slowly sorting through all my tubes for the last few months and came across some of my CRT collection. I figured it was a great time for a photo so here are most of them. I know a have the little 1" RCA 913 somewhere, but can't find it
I can't find a few 3" scope CRTs either. Oh well, they've got to be around somewhere.
Mostly these are from 'scopes, radar and other specialized test equipment. Some have cool phosphor colors like purple and orange. Then there are the HUGE 12" electrostatic 12FP7 radar tubes in the background.
3JP12 orange phosphor
3HP7 magnetic deflection radar tube
5SP7 dual-gun radar tube
Early Japanese CRT
Radial radar CRTs - 3DP1+S2
Infrared night-vision tube from 1952
That got me thinking - the basing and voltage specs is pretty close to a 7JP4
Time to try one out! I'm going to have to make an adapter first. The 6KV needs to be routing out of the socket and out to the ultor.
