What is best way to learn to build own equipment?

I wanted to learn how to build my own stereo equipment. I live in Southwest Missouri and I am able to find schools that provide training in electronics. The only thing I have been able to find so far is a weekend program in Chicago that teaches how to build a tube amp.

Does anyone have any suggestions on how the best way to learning how to build your own equipment? I open to any type of training, books, online information, etc.

Thanks for your willingness to try to help me.
