Now, if you want to "build from scratch" totally, you
will have to learn to SUCK all the air out of the tubes
you build for yourself (honoring the "tradition").
That's rather difficult (truly, vacuum sucks)...but
much, much easier than first creating ultra-pure
silicon and then doping the microscopic areas on it to
become the solid-state device you need. [sorry you
can't build "spark" transmitters...those being forbidden
in these modern times unlike a hundred years ago]

It's so easy to look up facts nowadays, I'm surprised that you were
unable to find this: "A 17-year-old named Haddaway had built his
entire station from absolute scratch, including the making of his
own vacuum tubes...." QST February 1921.

See? Fact, not an opinion attempted to be passed as a fact. You should
try that sometime. But then that would be impossible for you, for
you'd have to list references.
