Rca 914 crt

[toober]

I was helping a buddy organize one of his goodie piles, and we found a big, beautiful RCA CRT, type 914. It looks like the design is prewar - big pin base, electrostatic with the four plate caps out the sides - but his was clearly made after World War 2, probably late 40s. It looks to be 9 inches or so, and either P1 or P4.

A tag on the box says "for 305 scope". Scope? That is a damn big tube for scope. I know RCA made a few scopes with 7 inch tubes, primarily for schools, but I have never seen a scope with a 9 inch tube.

So, I am thinking this 914 was made for television use. Does anyone know of any TVs that use this oddball?
