Bright Switch Lecture - Egnater Amp Building Seminar

If you’ve never worked on a tube amp, it can be hard to find your way into understanding how they work. Somehow, we create a tiny signal by making metal strings on our guitars oscillate over a magnet wrapped with a coil of wire, and our amp takes that electrical signal and gets it to drive a speaker. (And driving the speaker is basically the opposite of how the signal started: It is a coil of wire moving within a magnet, which drives a speaker cone that moves air.) I’d like to simplify some of the processes that go on in our amps, so even if you’re not an expert, you’ll have some idea of what’s going on.
