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.

go to www.sonicfrontiers.com
get on the anthem side of the site and search for
"A Taste of Tubes". Awesome reading.

Go to the discussion forums here as well as the sale items and educate yourself. Your can get an idea about what to buy here, how to set it up and you can ask questions as well.

This forum is as good as any book. You can see what people value in the present time and consider to be good sound. Look at McIntosh tube amps, Audio Research tube amps, etc.
