On the subject of degaussing, I used to like doing that on the old CRT monitors.... it was like a mini earthquake on my desk. Although these days in NZ, we get pretty of real quakes every day...

Hehe, yea, our old tube TV we had when I was little had a purple discoloration in the corner from that...

I seem to remember a bunch of knobs on my grandmas old TV (oh how I wish I had an old TV to rip into... all those parts...), but I've never had a TV with anything but buttons. Our newest TV doesn't even have those.
One of the televisions we had when I was younger had a manual rotary tuner. No pre-set positions at all: it worked just like tuning a radio, with the added complication that you were tuning to get an acceptable picture as well as sound. It was not a great set even by the standards of those days, and the picture controls might need to be readjusted more than once in the course of an evening as the set heated up.

My poor old mother could never really master it, and she was very pleased when the next set we got had push button tuning, and a picture which would actually stay in lock.

Nostalgia...

Horizontal and vertical hold, color intensity and tint, seperate VHF and UHF tuners with fine tuning knobs, sound volume, and sometimes a tone control. In the back we adjusted the FM coil to get the sound right, red, green, and blue drive and red, green, and blue brightness(?), ground a pin and adjust the color oscillator so it synchronized with the least amount of feedback, same with the horizontal oscillator, CRT anode voltage and focus voltage, about 16 adjustments to get the R, G, and B lines to track together on the screen, at least 2 tabs on the yoke to get the "purity" right, and probably a few I forgot.

@ 12, Adjust the coils to bend the lines at the outer edge of the screen.
When you made one turn it would change some thing else,you could
never get a head..no perfect convergence.

It's just that old saying - maybe it's more of a NZ / Australian thing? - when someone's being led up the garden path? A bit too obtuse, maybe :)

Around about November I hope to have a book out featuring all of the cartoons (there should be 160 - 200, so it should be worthwhile). I have found a site where the author can upload and create the book, and folks can buy it if they want (direct).

Here on the other side of the world, you are led (LED?) down the garden path. It is, however, a rather old phrase.

:)
