Hi everyone, After having to take various tube amps to my amp guy five times in the last year and a half or so, I have decided that I need to learn to do basic maintenance work on my amps. I was wondering if oyu have any good recommendations for DVD and books. Some that also have some sections on safety when dealing with guts of the amps would be great too! What I have been leaning towards DVD: Tube Guitar Amplifier Servicing & Overhaul - Gerald Weber Book: Guitar Amp Handbook - David Hunter Any other good ones? Also what are the basic tools I am going to need? I do have some experience wiring Tele and Strats but beyond that I have no experience with electronics. Thanks!
