Eimac produced a good book called "Care and Feeding of Power Grid Tubes".  I'm sure I saw a PDF somewhere so it's worth googling to see what you can find.  About 20 years ago I wrote to Eimac and asked about the book's availability and they just sent me a copy.

The W6SAI 'Radio Handbook' contains some good information on the subject.

If you can't find a copy of the Eimac PDF on the www then give me a shout and I'll see if I can find a copy for you

Subject: [Amps] Tube Theory?

Hello,

   Anybody know a good book to get on tube theory?  I'd just like the
basics on how to go from a set of specs and curves to a design.  I used
to know this stuff but that was a LONG time ago.  We recently moved -
and I can't find a lot of stuff.  Including my 70's college textbook on
devices and circuits, which had a good treatment of it.  Load lines,
plate resistance, quiescent points, interelectrode capacitance, etc
etc.  Can't find it anywhere.  I did locate my two copies of "The Art
of Electronics", but they don't say word one about tubes.

   I have several ARRL handbooks from the 50's to the latest one.  Don't
know if there's enough detail in those to actually design anything.

   I see that "The Care and Feeding of Power Grid Tubes" is now available
as a free download...
