I visited an exhibition about 1966/7 at Mullard in Torrington Place where they showed prototypes from several manufacturers but I’m not sure if these were all valve.
I attended a lecture by Mazda about the same time about all the different types of colour tubes that had been invented. Most of the patents were owned by RCA who seemed to try and make sure they had a monopoly. They had a colour TV on show but I don’t know the make or whether it was PAL or NTSC nor all valve but I don’t think it was a Thorn 2000 prototype.
