1961 hand held color tv?

[julianburke]

Remember that in 1961 they were still into 21" round tubes with no rectangulars in sight. I doubt seriously their technology at that time could have produced the tube that ETF has at that time. It looks like something from the later '70's to me if that early. Remember SONY had that flat CRT in their "Watchmans" only in B&W in the '80's some 25 years later. COLOR flat tubes in 1961?? I don't think so as they were not that advanced. B&W I may hardly believe that, but not color. There was too much geometry in that tube to understand in 1961.

I would like to know what they were doing then if I am wrong here. There were no IC's back then and only IF they used discreet SS parts available then, there is no way in heck they could put them all in that hand held TV!! Perhaps there was a huge backpack to go along with it! Even so, CRT design was not that advanced for color back then. OK guys, prove me wrong here!!

BTW, just where would the shadow mask have been???
