The Impoverished Radio Experimenter, Volume 1
Experimenters notes on Vacuum Tube Substitutions, Inexpensive Tube Power Supply, Grid-Leak Detectors, Regenerative Receiver and more!
Vacuum tubes are to the electronics industry what steam locomotives are to the railroading industry: hot, inefficient maintenance headaches. But like a steam locomotive, a tube has a simple fascinating charm that no high-tech chip can match. You must try building a simple radio with tubes!
Here are tips, hints, suggestions and secrets for substituting common inexpensive tubes in early circuits. You also get details on a crystal set that was converted to a grid-leak radio. You'll get details on how various tubes worked in the circuit. Then you'll be shown how to build a simple and cheap power supply that will power a two or three tube radio.
You get pages of tube charts and basing diagrams, a reprint on tube theory from 1931, a bibliography of research papers from the late 20s, and you get a brief demonstration of a one-tube regenerative receiver built witha 6SN7 glass tube from the 1950s using a circuit from 1927. It uses a home-made variable capacitor and the home-made power supply described.
