There are resellers selling old print copies of Vacuum Tube Amplifier Basics, ISBN: 9781500938864. Some of these old copies are selling for ridiculously high prices. The old print versions were not of the best quality and were printed before the text was checked for grammar. Also, some of the covers may make reference to different editions; they are all basically edition one with some updates. The new second edition above was carefully assembled over several months and is less expensive than older print versions. In addition, images in the old print books were all black and white. Several images in the new second edition are in color, including the project layout drawings at the back of the book.
