Jeff, I think being the A/V Guru in High School may be almost as good as being in Band.
You go to numerous events and get some respect if you're any good at all. I was in VoTech, so I missed out on those experiences.

We had a Setchell Carlson 23" BW Monitor in the Library of my elementary school. The kind with two big speakers under the CRT with the controls clustered in the middle. Saw the inside of one at VoTech, a very impressive hand-wired modular design!

Generally, only two kinds of RCA sets were universally used in the middle and high schools. The first was a 23" BW, metal cabinet, hard plastic back and 1968-ish knobs. The color sets were 1975 RCA 25" XL-100s model JU970, I have one recently rescued from a project and a newer Colortrak from 1986. RCA's finest work in the later years IMO

Over the last 15 years, I was part of the architects' design teams for public school projects. I had to design the power and pathways for all things copper and fiber. Unfortunately, I was onto the next job and rarely saw how the AV department outfitted and used these studios.
The newest thing I saw in the last 6 years is a web-based video server that is networked to classroom PCs to video projectors with smartboards.

The standard AV space is set-up as a small studio with theatrical lighting. The control room has a long countertop and window to the studio, then loaded up with video switchers and monitors for editing. It probably rivals local TV stations.
My job was to interview the teacher before a major construcion project and make sure the "blue prints" reflected what they were prepared to fit out and use. Universally, there are floor power/ethernet outlets in the studio with "mouseholes" for AV cables running across the floor into the control room. The control room has wiremold outlet strips along all the walls and above/below the counter.
I never heard anybody complain there were too many power receptacles.
I also saw many a collection of Zenith, Panasonic, RCA and Sony CRT sets on carts wasting away in basements, storage rooms and warehouses. On a recent project, the sets were donated to Haiti relief efforts.
