That's an easy question, but could be hard to answer.   Old 
electronic text books are good.  Looking around my book shelve=
 over 
here I'd say an easy start would be something like the RCA=
 receiving 
tube manual, any of the various editions , reprints are=
 available.  
The first 60 or so pages are on tube basics.  It is also presumed=
 
that you've got some electron theory under your belt.  It does=
 make 
for a better understanding.  After that the skies the limit on=
 book 
learning.  Radiotron Handbook is excellent.  I'd stay away from=
 from 
90% of web sources.  Most of what I read makes me blanch.  That's=
 one 
curse of the web...too easy to communicate knowledge, including 
garbage, which often comes out the other end as gospel.  
One thing I do know is you can never learn enough about=
 electronics 
and it can be enjoyable.

Helm.
