Grigsby-Grunow produced radios under the trade name of "Majestic." The Majestic Model 50 is a tabletop, vacuum tube, superheterodyne radio receiver of the popular 'tombstone' configuration. The example to the left is from an eBay listing.

Majestic "Models 50," "51" and "52"

The Model 50" chassis is used in the "Model 52" Majestic superheterodyne ; removing the legs from the small cabinet, thus making a radio set of the mantel type, results in the "Model 51" receiver. This circuit is one of the latest developments of the Grigsby-Grunow Company, Chicago, Ill.

Tune in a station at approximately 1,280 kc. and align the oscillator and antenna or band-selector condensers C5, C8, C9. Next, tune in a 600-kc. signal and adjust the tracking condenser C6, while slightly rocking the tuning condenser knob from side to side, until maximum signal strength is obtained.

The manufacturers advise that under no conditions should an attempt be made to use a ground connection on the antenna binding post.

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...
