R.E.T.S. Instruction Course in Vacuum-Tube Radios on CD

Price: $9.95

This CD is for you if you have an old radio or a collection of old radios and want to learn how to fix your own, or just want to get to know more about electronics. If you spent about an hour a day for about two months with this CD, you would be able to go though the whole course of study. You wouldn't be an expert, of course, but you would have a very good grasp of how radios work, what usually fails on them, and how to diagnose and fix them.

This is a complete study course; the subject of which is electronics with a focus on the vacuum-tube radio. The course was used by R.E.T.S. (Radio Electronic Television Schools) in 1961. R.E.T.S. had schools in several locations around the country.

Students would attend school in a classroom and laboratory setting, and take home assignments. During the course, the students would build a 5-tube Superheterodyne radio as they progressed.

This is a scan of the manual used in the course. It's not necessary to have any electronic parts available, nor is it necessary to build a radio as you go along through the lessons.

The lessons start out with a discussion of different types of soldering guns, the proper way to connect wires, and proper soldering techniques. From there, it takes the student through the theory behind the transmission and reception of radio waves, but not so much that one gets discouraged by unfamiliar terminology.

Then the student is introduced to the 5-tube (most common) radio. Detectors, vacuum-tubes, and the various stages in the "modern" radio are discussed, what each stage does, how it functions, what the various components are, and why the particular values are chosen for each component.

After the radio discussion is complete, the lessons discuss troubleshooting and repair, then an introduction to Frequency Modulation. (FM).

The CD opens automatically when inserted into the computer and displays a menu (not on Macintosh or possibly new versions of Windows 10. From there, an Adobe PDF file opens with the lessons. Each lesson title is labeled and bookmarked within the PDF so you can easily navigate through the lessons. Individual pages can be printed if desired.
