I am looking for sites/books/videos to learn about building audio components like amps, switches etc. I have a mechanical engineering background and am in the middle of an amp build with premade boards and power supplies. But eventually I would love to design and solder my own boards, like a preamp with volume & input control and display.

Many on-line basic classes. DC, AC, Transistors, Circuits usually in that order.
To understand amplifiers, the books by Cordell and Self are the SOP. Leach does more of the raw math theory. If you don't understand something they are talking about, GOOGLE it and find a course or description of it. he world is at your fingertips. Your engineering library should have all of that.

Download a copy of one of the Spice programs. I use LTSpice. So you can simulate and play with what you think you are learning.

At least as an ME, you will have the math and no one has to explain imaginary numbers to you. Gives you a big leg up.

Read, watch, experiment, make mistakes, learn, be patient. I figure I'm 2 years into a 6 year journey of really knowing what those electrons are doing swimming around in the magic smoke we try to keep bottled up in resistors and capacitors and transistors.

Books:

20 (30?) Years ago I picked up Design and Construction of Tube Guitar Amplifiers by Robert Megantz which focused on fundamental electronics from "what's a volt?" straight through to design parameters for building all sorts of tube amp architectures. These concepts, as you learn them, apply whether the amplifying device is tube or solid state.

A Practical Introduction to Electronics Circuits by Martin Hartley Jones is a college level electrical engineering text book from the 70s that introduces concepts and then uses my favorite phrase in the English language, "For example."

Many, many excellent learning resources on YouTube:

W2AEW seems to be a Ham radio enthusiast, but has hundreds of videos explaining a simple circuit on pen and paper, then going to a breadboard and meters to show how the concepts work:

Simply Put's very unique style has helped me learn electronics

Uncle Doug is a national treasure focused on Tube concepts, but these concepts translate quite well

From a building / wiring / testing of amp circuits, building the rpojects you find here at DIYAudio,

Many good repair / diagnosis folk out there too:

Mr. Carlson's Lab is the Bob Ross of discreet electronics paining

Duality Repair is great at helping you reverse engineer a schematic

12VoltVids gets to the point without all the perfectionism. You can learn a lot from this feller!

You know, I might be at the point where I need to do that.

Another great free online tool is
http://www.falstad.com/circuit/

Where you can build out circuits from discrete components and see what happens. It helped me "see" what was really happening in a virtual breadboard sort-of way.
