Audio Amateur Publications have tons of books geared to people of all levels of knowledge from newbie to expert. They have a website. Radio Shack used to carry a few books for beginners. Don't know if they still do.
Electronic Circuitry For Dummies
I've been through all 686 thread titles in tech Talk and can't find anything on circuits. Can anyone recommend a book or books that explains what resistors, capacitors, etc do and how electricity becomes an audio signal? I just want to understand how my amplifier works and maybe get a handle on things like what biasing tubes does to the signal.
