I wasn't around when roundie CRTs were being made, I really wasn't even around when vacuum tube sets were being produced, everything was pretty much solid state when I was born in Feb of 1978.. My mother had a cheap B/W tube set when I was a baby, it's in a picture somewhere I believe.. But she said I use to go in the back of the set and mess with the knobs.. I may have even broke the set LOL.. But there is something about roundie and old sets I really like.. I like them from the beginning to the early 80s, when they started to become digital, I didn't care for them... I do like some of the early digital Zeniths with the digital tuners and green display readout, which I have one of those sets.. But I remember always wanting a color roundie as far back to the late 1990s when I got my first B/W roundie I believe from that guy that owns this site:
http://www.vintagetvsets.com/ pretty sure it was this site or maybe someone related to it, I remember viewing that site in 1998, or 99.. It really looks no different.. But it was a guy out of Long Island New York.. I never recall ever seeing a color roundie working as a kid, and all TVs I saw in the junk back in the 80s were early rectangular sets.. Web surfing in the late 1990s and seeing actual pictures of color roundies actually made me want one, and it was only up until about 3 years ago until I saw one operating in person...
