Thought you might like a trip down memory lane…
in the presentation mention is made of tubes being tested
in such a manner to determine durability…some 5000 hours some 10,000 hours
some 50,000 hours…wow
Enjoy

I’m old enough to remember RCA TV technicians coming to our house with a satchel full of tubes when our 21" black and white RCA TV “went on the blink” and needed repair.
glad you enjoyed the trrip down memory lane…
My family’s black and white RCA was
huge, heavy, blew a lot of fuses (the screw in kind), and only caught on fire once!
When my mother wasn’t swearing at it because of repairs needed she was swearing by it as the best babysitter she could’ve asked for.
I remember watching test patterns on Saturday mornings until the cartoons started and the National Anthem was played.
Oh, yes. Andy’s Gang, Sky King, Fury and all the rest.
Don’t forget Howdee Doodee and Buffalo Bob.
Oh, never could forget them. Simpler times, for sure.
Roy Rogers, Rin Tin Tin, Gene Autry and many more…
Don’t forget Hopalong Cassidy!
Different programs but similar memories. I used to particularly enjoy the transmitter information cards in the early afternoons.
Years later of course we all became teletext addicts…
I remember when I was a child, my father had a problem with our TV. He took the vacuum tubes out and we went down at the local drug store where they had a tube testing machine like the one above. Then he would test each tube until he found the bad one. The machine was stocked full of replacement tubes.
I remember my grandparents all tube television with a mechanical clicker remote. In a way, the craftsmanship and manufacturing expertise that went into mass production of large diagonal size tube displays themselves was remarkable.
