Yes, its absolutely true that the picture on an old color TV can look better than on even a CT-100 or 21CT55 back in the day, in the RCA labs in NJ, connected
to an antenna with a really clear view of the Empire State building.
This is because silicon chip cameras are so much better than even the best adjusted image orthicon looking at a daytime scene such as a baseball game.
But other than that, if they had a modern camera, the image on a set, with
all the set's adjustments done correctly (81 for a CT-100), all the adjustments in the transmitter (with a modern camera directed to the transmitter itself) would likely look just as good as what I see on my own set.
On recent dry days, with the line voltage running 117 volts, my CT-100 has been making great picture, with really near perfect convergence, and obly a bit
of purity problem which is visible only on a B&W picture.
The set at the ETF has on occasion been as good for everything except convergence.
But one thing is true of my CT-100: its ATSC ... "Always the Same Color",
not dependant on humidity (which is the source of convergence errors.)
