Take a look at the books for sale at www.audioxpress. They have most of the books available.
They also have a "classroom series" of very good articles online for free. These are old articles but still very good ones. www.audioxpress.com/resource/audioclass/index.htm
Two books that are both good and often recommended are "Beginners Guide to Tube Audio Design" by Bruce Rozenblit and "Valve Amplifiers" by Morgan Jones. Both are very good. I think the Jones book is the better(If only because it's longer (480 pages v 100 pages) of the two but both are worth buying and they tend to reinforce each other.
You will need a basic book on electricity too if you do not already have one as both texts take certain basics for granted. Lots are available try "Basic Electricity" by Van Valkenburg, Nooger & Neville available at www.samswebsite.com. For more advanced try "The Art of Electronics" by Horowitz and Hill.
Good Luck,
