My grandparents had the same exact TV when I was growing up, and they used it until it got struck by lightning back in the late 1990s or early 2000s when they then moved it out to their chicken coop (they lived at an old family farm stead that was built by my gr-gr-grandfather in 1920) and its been in the chicken coop since. I always wanted to try and dig it out of their chicken coop and try and fix it up but its kind of burried in their and also the chicken coop is starting to fall down, so I don't think its going to be salvagable unfortunately.
My Grandparents had an old front loader VCR from the early 1980s that had the old style Varactor Tuner built into it hooked up to it that I remember watching movies on it when I was a kid whenever me and my sister would stay the week or weekend with my grandparents, and also they had an old Atari 2600 hooked up to the TV for a while (but I never got to play it because they had it put away before I was old enough to know what it was.)
