There is a theoretical adavntage to them. Some of them are very quiet and have exrtremely high transconductance. In the early 60's, not much could touch them for an RF front end. There are glass tubes with similar performance, but I think they came along later.

I have two RCA portables connected to cable. These have the nuvistor tube as the RF amplifier and work well on cable. I have also connected GE portacolors and a late 1960s Motorola B&W to the same cable system with much poorer results-inter channel interference, etc. Because of my experience with the above, I believe that they do work better.

There were lots of clones of the CTC-15, that's sure, but my nomination for most-cloned manufactured product would probably go to the Singer Model 15 sewing machine.

[Hmm. Interesting that both product numbers involve "15".]

Singer themselves made the 15 (with some incremental improvements and changes in finish/styling) from 1879 to at least the 1960's (!), thus making it their longest-production model, but it spawed *gobs* of clones, many from Japan. Find any Japanese-made sewing machine from the 1950's or 60's, and there's probably at least an even chance it's a Singer 15 clone.
