I believe he is referring to People Emitting Thoria Allthetime
Those failures were traced to contamination during tube assembly in a dirty environment
You seem to know so much about all this that you should be able to replicate the old Cetron 572B product. For heaven sake do it!
It would cost over $50K for the equipment to make a vacuum tube.
It's so sad that there really aren't local "tube stores" around anymore.
I used to have fun as a kid calling a store, "Do you sell tubes?" and they'd answer "of course!"
"Put aside a couple of fallopians for me, I'll be there in an hour..."
Some have built working tubes on their kitchen table. Some have rebuilt tubes at home. And some remain clueless.
When I tried to build a tube in the kitchen, it came out like a baked ham.
It was delicious, though.
Kosher is best and Im not even Jewish but raised around many, in Brooklyn and later out "on the Island"
I was born in Coney Island. One block away from Surf Avenue (AKA 'the boardwalk") Nathan's was right there along with Steeplechase and the famous parachute ride. I'll never forget the "peanut whistle" from the guy selling roasted peanuts to the entrance of the boardwalk. Those were the days.
Thoria is an acceptable and understandable shortening of Thorium similar to Cupro or Ferro, etc. especially as a shorthand encompassing the possible Thorium compounds that might be used such as Carbonate, Borate or Calcite since I doubt metallic Thorium is used. Anyone with the slightest familiarity with chemistry can comprehend what is referred to.
