If you’re as old as I am (52), I’m sure you remember the full-page ads for the National Radio Institute. They advertised courses purporting to teach you radio/TV repair. Well, now, NRI’s’ Radio Servicing Methods course is available for download. Unfortunately, it doesn’t say what year this course is from. My guess is that it’s from somewhere in the 1950s.
And if you were wondering whatever happened to NRI, Wikipedia says,
The National Radio Institute was founded by James E. Smith, a high school teacher, in Washington, D.C., in 1914. It was purchased by McGraw-Hill in 1968 and renamed NRI Schools. James E. Smith remained as NRI chairman until his death in 1973. McGraw-Hill announced in 1999 that it would phase out NRI Schools, citing “changes in the marketplace”. They ceased operation on March 31, 2002.
