Audels Radiomans Guide
by Edwin P. Anderson  (1945)

925 pages, "covering theory, construction, and servicing including television electronics".  It covers everything from sounds waves through basic electronics, PA systems (including a little info on a WE theatre amp), transmitters, car and aircraft radio, troubleshooting - you name it, it's in here.  Not a college text, this looks like it could be a handbook for the radio technician or advanced hobbyist of the 1940's.  Lots of good vintage info!
 

This book is in PDF format for easy reading and is distributed on CD.
