Public domain technical books published before 1964
.org home Technical books online! 4.22 gigabytes and still (slowly) growing! Over 100 titles! Preserving the Knowledge of the Ancients? I've found that most of the technical books published before about 1964 never had their copyrights renewed, so now are in the public domain. So I am endeavoring to digitize and post some selected books relating to the "vacuum tube age" of electronics here.
Starts with the basics - electricity, radio, tubes - then delves into radiotelephone and telegraph transmitters and receivers, direction finding, navigation beacons, even VHF instrument landing systems. A bit more than a manual for your DMM, this talks about meter movements, and how they work, as well as measurements of voltage, current power, and resistance in typical radio and TV applications. 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.
