The Navy Electricity and Electronics Training Series (1998)
The Navy is good at training; I assume the other branches are as well.  The Navy took both of my grandfathers, one urban, one rural, both very poor, both of very modest education but apparent potential, and in months turned them into electricians.  They both made careers of being in the Navy based on that training, one as an electrician and one moving into logistics, both becoming Master Chiefs. They had the 1940s versions of these books and I learned a lot from them.
