I am a musician, so I've been talking about guitar amplifiers, tubes, microphones and all kinds of gear for over 20 years. I've never really gotten that much into PA's, so I know nothing about speakers, heads, mixers, power amplifiers, etc. Now, I'd like to build my own powered PA speaker. I have zero experience with building anything that involves electronics. I'm not a dummy. I know Ohm's law, and I believe I can handle the physics of electronics, no problem. I just do not know where to start. Schematics for power audio amplifiers? Where does one find them, and how do you read schematics. These are the things I need to know. Let me preface this by saying... I do not expect to build a top-of-the-line PA speaker. I don't even expect to build something that would be considered crappy. I just want to know the theory, and where to start. Anyone got any help? Thanks!
