1972 GE portable
Somewhere in the dim recesses of my barn, I have a 1972 vintage GE 12-inch portable black-and-white TV that I rebuilt when I was taking electronics in high school. When my grandfather gave it to me around 1980 or 81, it worked, but just barely. There were two more sets just like it in the back of the electronics lab at school and the teacher gave them to me to cannibalize for parts to make one good, working set out of the three.
I haven't turned the thing on in probably 20 years but I don't have the heart to trash it. I tried to give it to Goodwill a few years ago and they said they didn't take any TVs that didn't have a remote control. More recently, they stopped taking TVs with a CRT screen and now they just don't take TVs at all.
I also have a 1996-vintage 25-inch Sears LXI (re-badged GE) set that has now joined the little black-and-white set in the barn after 20 years of flawless service. Like the 12-inch set, nobody wants it and I don't have the heart to trash it. All three TVs in active service in the house are now flat panels (40-inch Sanyo, 32-inch HiSense, 24-inch Samsung). I'll be very, very surprised if any of them last 20 years.
