For the last few years I have been scanning and posting Radio Service Data Sheets like this one featuring the Belmont 4-Tube Model 408 (Series A) Battery "Farm" Superhet radio in graphical format, rather than run OCR on them to separate the textual content. It appeared in the October 1938 issue of Radio-Craft magazine. There are still many people who restore and service these vintage radios, and often it can be difficult or impossible to find schematics and/or tuning information. No example of this radio could be found on the WWW. I keep a running list of all data sheets at the bottom of the page to facilitate a search.

Belmont Radio Corporation: A Brief Overview and Historical Context

Belmont Radio was a leading American manufacturer of radio equipment during the 1920s and 1930s. The company was founded in Chicago, Illinois, in 1923, by Harold J. Belmont, and quickly became one of the largest radio manufacturers in the United States.

Belmont Radio was known for producing high-quality, affordable radio sets that were designed for both residential and commercial use. The company's radios were characterized by their distinctive cabinet designs, which were made from beautiful, handcrafted woods and came in a variety of styles and finishes. Belmont Radio's radios were also equipped with advanced technology, such as high-voltage power supplies, which allowed them to produce clear, powerful sound.

Belmont Radio was a major player in the commercialization of radio, and the company played a key role in the growth of the radio industry during the 1920s and 1930s. The company was an early adopter of the use of advertising to promote its products, and its innovative marketing campaigns helped to bring radio to a wider audience. Belmont Radio also played a role in the establishment of the National Broadcasting Company (NBC), which was founded in 1926, and was a major factor in the growth of commercial radio broadcasting.

In addition to its contributions to the radio industry, Belmont Radio was also a leader in the development of new technology. The company was one of the first to develop the "breadboard" radio set, which was easy to assemble and repair. This innovation made radio more accessible to a wider audience and helped to increase the popularity of radio as a means of communication and entertainment.

Despite its success, Belmont Radio faced challenges during the Great Depression, and the company eventually merged with another radio manufacturer in the 1930s. However, the legacy of Belmont Radio continues to be felt today, and the company's impact on the radio industry is still remembered.

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.

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...
