Tom, sorry my innocent inquire broke your Silvertone! I must be more careful in my future posts. Thanks again for your interest in my inquiry and your great screen shot postings. Anyway, I now believe my 21FBP22 can't possibly be a 21GUP22 since I bought it in '64 and its " nonactive screen color" is definitely "paper-white" indicating rare-earth as miniman posted. Its most likely a "rare-earth" 21FBP22A as I always suspected and stated in my posts. So is that good or bad from a Picture Quality standpoint? Are the saturated reds of the rare-earth 21FBP22s more like the 15GP22s and 21AXP22s then the more numerous olive-green screen sulfide 21FBP22s? The last time I saw a 21AXP22 was my Dad's CTC4 when I replaced it with my present 21FBP22A 48 years ago. In fact, I haven't seen another roundy of any kind besides mine ever since. All I know is my 21FBP22A reds are obviously more "RED" then my 13in Sony Pro monitor which has SMPTE-C phosphor and my 27in Sony comb-filtered monitor. Both Sonys are orangeish-red in comparison. I was told the SMPTE-C reds make the reproduction of flesh-tones more natural? I would like to see a rare-earth, paper-white screen 21FBP22 included in any serious comparisons with other 21in roundy including Tom's 21GUP22 and the original 15GP22s.
