John Larkin doesn't seem to 'design" anything. He throws together the stuff he sells like every other tinkerer.

Why does that matter to you so much?

I have two books in front of me.
One is "Introduction to Solid State Physics, C. Kittel"
The other is "FET Circuits. Rufus P Turner"

I wasn't bad at math and can handle contour integrals but it is also true that I grew up in a very practical electronics
environment
where getting things working was way more important than understanding every little detail of the theory of how they worked.

So both of these are needed if you want the best design.
Not really. Understanding at some level can help a lot, but it's not
necessary. Besides, we don't actually understand what we're doing, all
the way down to the quantum mechanics.
