This ad for the 1962 model RCA New Vista sets is based on Disney's Wonderful World of Color, but the most interesting thing to me is that they specifically mention the sulfide picture tube.

That would have been the CTC11 chassis with a 21FBP22 CRT, correct?

Was rare earth phosphor only in the 21FJP22 and considered a further improvement than sulfide?

Maybe someone who knows for sure can answer - my impression has always been that the 21FB and 21FJ got some phosphor modifications at times without changing the electrical characteristics or the tube number, but I don't know.

What tube number were the first Sylvania rare earth roundies?

From what I've read Sylvania introduced their line of '65 color receivers in June of '64. These '65 models were the first to employ Sylvania's new "Color Bright 85" picture tubes using Sylvania's new rare-earth red phosphor. I don't have an exact tube/part #. Pretty sure these were 21" round tubes. 25" tubes were used starting w/the 1966 models.

Yes, the first Sylvania tubes with rare earth red were round; I have ads saying that; but the tube number is not mentioned.

21FKP22, I think. The red on the one I had trended to a pink, not an orange. Go figure.
