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.
