The problems with vacuum tube amplifiers are varied, and it can be a great help to see what problems have been seen before. This book is a list of repairs, sorted by Make and Model to make it easy to find a particular unit you may be working on. This book can help in the understanding of failures in vacuum tube audio and other equipment, and their resolution. I tried to explain what happened, why it happened, what it took to resolve it, and what I did to keep it from happening again. These are actual cases of repair, over 2500 of them, mostly vacuum tube guitar amplifiers, but you will find other equipment in there as well, such as audiophile amps and effects.In this version, I have included a list of parts used to complete the repair. A good description of the part is given, enough to locate the part at a distributor. There is a small addendum with sources for schematic diagrams and some parts distributors that I use often.
