Some one talled me that he had seen on the internet and all tube/hybrid tv set, that had and screen 31"-32" and had 100,000 V anodic voltage! :sigh: (the 100,000 V where delivered by 2 wires, each of them delivering 50,000 V). A set like this ever existed?

I think someone is shooting you a line of bullcrap. The biggest color TV that I've seen that used vacuum tubes was a 25". Sony came out with a 26" CRT set (solid state) in the very early '80's. The oldest 27" CRT set I've seen was a Zenith from around '85. The larger CRT's didn't really take off until the late '80's.

Just think of all the X-Rays that thing would produce at 100KV if it was real...
25V was the largest for tube sets. I never saw one with HV above 25-27 KV.

saw a 31" quasar at suns back in the early to mid 80s.nice console.great picture.couldn t get them down to my budget.i think in 1984-85?

Maybe a one-off experimental job, maybe done just for showing off the technology? Maybe something out of the old Soviet bloc? Did they say if it was color or bw? I have heard of projection sets approaching 100kv.

110 degree 26" (delta gun) CRTs were made by Philips as early as 1971, in 1974 they also made the excellent 20AX inline version.

Their first 33" CRT was the 1985 45AX (the first CRT with square corners)

My guess is that somebody is now calling CRT + solid state chassis TVs "hybrids". That would explain much of it.

uuhhmmmm in my opinion this is an urban legend, like the crocodiles in the sewers of new york :D

Be aware there were 30" CRT sets in the early 1950's from Zenith and DuMont,

Black and White, of course.

You mean the second anode at +50 kV and the cathode at -50 kV? Sounds like
the urban legend someone else mentioned.

Sony made a 4:3 - 41 inch Trinitron color monitor in the 1980s probably used mostly in TV studios for the talent. It had 35KV on the ultor and weighed
over 200 lbs.
