June 1936 Radio-Craft

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

The thumbnail image of the International Model 77 'Kadette' radio is from the RadioMuseum.org website. Below is the Radio Service Data Sheet as it appeared in a 1936 issue of Radio-Craft magazine. This floor-sitting console model is typical of configurations of the day with a tiny dial buried amongst a large wooden chassis.

See Tom Bavis' AudioPhool.com website for an extensive collection of Stromberg-Carlson photos, datasheets and Sam's Photofacts files.

Radio Service Data Sheet

Ranges: 540 to 1,500 kc., 1,450 to 3,500 kc., and 5,600 to 18,000 kc.: speaker rectifier; wave trap; tone control; pentode output tube.

All measured from respective elements to ground. The line voltage is 120. The table voltage will be slightly lower when the receiver is connected to a D.C. source.

An antenna trap circuit keeps out code and other radio interference, which otherwise might be reproduced through the l.F. amplifier circuits. Note use of pentode out-put, V5. The receiver draws 65 W. from the line, and the power output is about 1.5 W.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 227 Radio Service Data Sheets as of December 28, 2020.

About RF Cafe Copyright: 1996 - 2024 Webmaster: Kirt Blattenberger, BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. 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...
