Its not amazing at all. The RCA set, the CT-100, was essentially cost no object. The others had some simplficiations, but the Westinghouse
and a couple of others had straightforward, no tricks, color chains.
At least RCA and Westinghouse had adequate adjustments and feedback
adders to reduce tube gain changes. And they had real DC restorers.
RCA in fact really needs only one more control to have a full set,
assuming close tolerance resistors in the matrices. Those two are capable of
very, very close to modern quality RGB signals. The major problem is that
one has to drive the red CRT gun so much harder than the other two that
the don't perfectly match curve shape.
