We had an Admiral TV set in the mid 50's; probably when I was about 6 or 7 yrs old.
2 knobs; Vol and Channel. I think there were more controls, but we were advised to never touch them.
I recall the test patterns as well........meant the end of the telecasting day.
Of all the ads on TV at that time, I remember the Hamms bear and the jingle "From the land of sky-blue waters" I see that it's on YouTube, but of course with a lot of other ads.
One time, my sisters and I were doing some "crazy dancing" in the living room and pushed the set into the wall. As the narrow end of the CRT tube was sticking out quite a bit beyond the cabinet, it caught the brunt of the push, and was effectively disabled.
I was surprised my Dad didn't really get upset; as that would've been his normal reaction. Couple weeks later, back on.
