Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Craft, published 1929 - 1953. All copyrights are hereby acknowledged.

Here is the Majestic Chassis Models 380 A.C. T.R.F., and 400 A.C.-D.C. Superheterodyne schematic and parts list as featured in a 1933 edition of Radio-Craft magazine.

Even with the availability of SAMS Photofacts, there are some models that cannot be found anywhere other than in these vintage magazines.

There are 227 Radio Service Data Sheets as of December 28, 2020.

The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
