...and:
* There's not enough information about linear operation.
* There's not enough information about operation above 30MHz.
* It doesn't mention more modern tubes - even the 3-500Z came later than
the book, and of course there's nothing about the 3CX800 or 8873-4-5-7.
* There's no application information to put the principles into
practice.
... and above all:
* There's no information about anything that has happened in the last 35
years!
Eimac were absolutely correct to decide that C&F needs to be updated.
I wish they'd now decide that the dream about "let's all do it via the
web" has failed - and then either do it a different way, or not at all.
