Yes, Dynatron merged with Ecko in the 1950s who themselves merged with Pye in 1960. Philips bought Pye in 1967 but Dynatron was kept as a premium brand. The G11 chassis made by Pye was deemed far superior to Philips' own version hence it ended up in Dynatron TVs.
Most 12" black and white TVs of this era are very reliable. It's usually things like tuners and volume controls that go crackly and need a spray of contact cleaner. I did need to adjust the yoke on this one: youtu.be/_j8DiQX6-Tk?...

It's no more dangerous than working on a car engine's ignition system. In fact car spark plug leads hurt way more! If you look at the back of any CRT you'll see a huge rubber cup with a thick wire coming from it, that's the anode. Keep your fingers away from it and you'll be fine.
Vintage TV time! 1978 Pye CT450. Actually a Philips G11. Easy to repair as the boards hinge out and can be unplugged. As a kid I remember watching the man repair the one my parents had and was fascinated. This is what got me into repairing stuff. Even the Queen had one in a posh cabinet!
Don't make me dig out sexy Brian Eno!
I seem to recall red and blue were most common. Certainly the ones I had were! I remember customers complaining about adult services being ordered. I would ask if anyone else has the pin? "Just my 15 year old son but he wouldn't look at things like that." 🤣
Heh, the one on the right I had loads of different coloured "ends" for those for different players, nicked from when I worked for Telewest. Mad to think there was no restriction on the pay to play games back then.
