At what point in history were they named by their shape instead of their function


??? They were already being called Vacuum tubes, when they were
still special, in hand blown envelopes. the tubular envelope came
later.

? Typical Yanks.


Yes, we know that you despise America, and all that it stands for.
You've made that abundantly clear on all the other electronics
newsgroups.

Where do they say that? The phrase is, "You pay your money and you
take your chances."

Well, that's very educational.. Leave it up the brits to twist things
around.
Now I can understand thermionic valve description. We took that up in
school years ago in science class where we made a tube via a mayonnaise
lid with all the components on it and evacuated the jar. It was a very
impressive project. Used material from various sources to make the
heater, cathode, grid and plate that mounted on the lid.
Of course, it didn't perform like a properly made tube but it did
demonstrate activity of a triode when I was able to show that I
could control current via the control grid.

I do have an antique radio tech reference that is worth some money.
Maybe i'll brush through that book and see what else has been twisted
from the original electronic pioneers..

Btw, if my education isn't failing me, I seem to remember that Edison
was actually the first to discover the tube and didn't know it. His use
of a plate to collect the shoot was in theory the plate in a tube.

And whoever twirled a "cat's whisker" on a lump of galena discovered the
point contact diode but didn't know it - it just magically worked.
Like, who on earth would think of squeezing the contents of the swim bladder
of a sturgeon into a beer vat on the off-chance it would make it clear
quicker.

You think a lot like me. I've often wondered how things like you describe
ever came to be.
