Do "roundie" color sets make a better picture than later sets?

[rca2000]

I can't quite put my finger on it.....but there is SOMETHING about a roundie set. Particularly the Zeniths. I have watched enough shown on them to KNOW...there just look "different". I have seen things on a well working 25MC33 zenith..that just looked "out of this world" in picture quality !! (of course--this was over 30 years ago).

Maybe it is THIS. (just my opinion)...

Keep in mind...the gun structure of round color tubes is MUCH larger than rect. tubes. ESPECIALLY in-line ones. In FACT..ONE gun from a 21FBP22 or such....is LARGER--than all THREE guns physically of a mini-neck in line tube !!

This of course would seem to mean there would be a BIGGER--STRONGER beam to the phospor--which would seem to light it "better". Not necessairly brighter...just more vivid and lifelike.

Of course...NONE of this may be right..just my opinion and observations.

I would LOVE to see someone figure out some way...to show an HD program on a roundie tube. I just WONDER what that would look like?
