16GP4B Opinions

[kf4rca]

I have a 12LP4 if that helps. New Old Stock rebuilt RCA stock. Not aluminized round crt. Not sure what it fits. Maybe you could build an adapter or something.
Its been sitting in my utility room for the last 30 years or so. Had good emission last time I checked it.

The 12LP4 fits just about every late 40s to ~1951 12" TV. Dumont had a shorter neck tube and Zenith had a metal cone tube in that size, but a 12LP4 can be shoehorned in to those sets too. There's someone around Missouri or Kansas who was looking for a 12LP4.
Prior to the 16GP4 all US CRTs I'm aware of (20BP4, 16AP4, 12LP/KP/UP4 10BP/FP4 7DP4) used the same angle. Many chassis drove 2-3 of those types of different screen sizes unmodified. The 16GP4 is the oldest post war tube I know of that has an increased deflection angle to make the cabinet shallower.
