I think the seller may have made a small mistake in his/her description of that Zenith roundie we're discussing here. The round CRTs were only made in one size that I am aware of--21 inches. The seller quotes the screen size as 19 inches. I've been around televisions and electronics for over thirty years and have never yet seen a 19-inch round color CRT. RCA TVs of early 1950s vintage had 16-inch round monochrome tubes (16GP4), and Zenith's Great Circle Screen series used round CRTs as well, but to the best of my knowledge all round color tubes were 21 inches.

BTW, I think the seller is just trying to get the set off his/her hands as soon as possible, and doesn't know much or anything about TV or electronics. If, as some of you have said, the set has weak CRT guns or other problems in the chroma circuits, it is not "work(ing) well" as the seller said in the description. A color television with an off-color picture caused by chassis faults, including but not limited to defective tubes or a defective CRT, is not working well at all. IMO, the seller just wants to get rid of the set ASAP, and will do or say anything just to achieve that end.
