Why so Big

[6GH8cowboy]

I guess the coil to beam distance makes sense. I now recall some of the GE and Admiral 19" sets with the really small neck CRT's and the yoke was smaller too. I have a 4-1/2 inch orthicon tube that starts out the same size as a old color neck and gets much bigger down most of its legnth. I'm willing to bet the DY was huge or used a much higher amount of power to sweep, but then again it was only a 4-1/2 inch target at the business end.
