Beginners guide to tube audiio.

Do a search on Amazon. Most of the books that I have found on tube amplifiers etc are pretty technical. Frankly I found them virtually unreadable. They were most certainly over my head.

I also suggest doing some Internet research. There is an enormous amount of information - and opinion - out there.

The book Rodman links to is by Robert Harley who is the Editor of Absolute Sound. It provides an excellent overview of all things audio. He has published two other books on the subject as well. See them all at:
