Prpobably the best written and most helpful books are those written by
one Rainer zur Linde. Unfortunately they are all in German (one is
Dutch.) He speaks Dutch but not English and the one translation done to
date isn't that great.


3 of Rainer's 4 books are translated in Dutch, available via the
publisher Elektor.

There's another author that deserves mentioning: Menno van der Veen.
I can highly recommend his book "Modern High End Valve Amplifiers" to
any tube novice.
