Does it still have its original CRT? I don't know exactly how old your TV is, but if I had to guess, I would say at least 35-40+ years. (I knew someone in my home town in the '70s whose family had an RCA TV very similar to this one, which is why I am estimating yours is at least 40 years old.) If the set still has the original tube after all those years, it is truly amazing that you are getting such a great picture. My best guess, however, is that the tube was replaced at least once, as it is all but unheard of for a CRT, b&w or color, to produce this good a picture after 40-odd years, unless the set wasn't used much by its previous owners.

Even at that, forty-plus years with the original CRT and making a picture as good as yours is phenomenal. Most color CRTs have either become so dim after this length of time (if they produce any kind of raster or picture at all) as to require a brightener, or else the filaments in one or more electron guns have burned out. Again, I think your CTC25 is on its second CRT. If it isn't, I'll be very surprised.
