69 Zenith 22" B&W metal cabinet

I have a Warwick built Sears Silvertone, that uses the 22TP4. The CRT is Sylvania sourced and the set is a hybrid. IIRC, it's a 1974 model.

It's interesting to compare the 22" next to a 19" and a 19V and a 23". I still think it's odd that the 19" was totally replaced by the slightly larger 19V, but that they were still making 23" tubes (calling them 22V) when these 22" tubes (21V) were only 1" smaller, yet with a wider deflection angle it made a 22" set much lighter, less deep, way earlier to move around. I've never seen a console with this tube, but I wonder why they never used them in B&W consoles in the late-60s/ 70s.

The earlier 19" CRT's, both B/W and color were 18" sets, 180 sq inches.
The last of the B/W consoles had 22V CRT's and 110 deg deflection.

I THINK we had these as schoolroom sets in the elementary grades.

I'm 12 or 13 years older than you. There was never a TV in the elementary or high school, I went to.
In high school, they used 16mm movies.
Ten years later, I went to tech school as part of my electrical apprenticeship, no TV's there either.

We had TVs in my grammar school.

My teachers rarely used them either. Except for space shots, badly written anti-drug programs, or once, game 7 of the World Series.

You really went to a high-class school! Sport coats or blazers, dress shirts and neck ties. Quite a dress code!

No, it was a generic Catholic parish "prison" school. Staffed with angry nuns and civilian teachers, armed with rulers to hit you with. The sort of school George Carlin used to talk about

I liked my Catholic school a lot better than the public school, plus we were at least two grades, more advanced. They had mostly nuns and only one lay teacher. It was a small school, so the grades were doubled up. I got smacked, here and there, as I was a bit of a smart*ss.

Well, WE had 'em, starting in the 4th grade. The Gov't had just installed WSJK TV, channel 2, the PBS station, & part of it was to "Aid the classroom teachers" w/ additional programming. None of the teachers I had ever used it very much, they'd turn it on when there was a space shot or somesuch.

I have a similar set, but mine has a 21" tube, 1966 model with the slide rule UHF tuner. Last used to watch 9-11-2001 news coverage. Tried to fire it up a month ago , but I'm getting some arcing around the HV rectifier socket, need to get it cleaned out, it was covered in what looks like old cigarette tar..
