Title: A poor book, period
Review: Repairing guitar amplifiers, tube or solid-state, is not at all beyond intermediate to advanced electronic hobbyists-but you have to know electronics. You have to know DC and AC electricity, amplification basics, signal paths and how to read basic schematics _cold_,to have any hope of success. You also have to be competent at both "wire and panel" and through-hole PCB soldering. You should also have basic test equipment, not only a good multimeter but a signal source-not a guitar!!- a dummy load, and at least a signal tracer but preferably an oscilloscope of some sort. For a lot of reasons, I tend to judge technicians by how competent they are with an oscilloscope, the overwhelmingly single most important test instrument. (Even deaf people can and have successfully built and repaired audio gear with one.)It can be learned from books and practicing-but not from this one.
