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

Belmont Radio was a manufacturing company that produced a range of radio equipment, including radios, amplifiers, and speakers. The company was known for its innovative designs and high-quality products, and was a leader in the radio industry during its time.

Founded in the early 20th century, Belmont Radio began as a small company that produced simple crystal radio sets. As radio technology advanced, the company expanded its product line to include more sophisticated radio equipment, such as amplifiers and speakers. Belmont Radio also developed its own patented radio technologies, which helped to set it apart from its competitors.

One of the key innovations that Belmont Radio is remembered for is its development of the "All-Wave" radio, which allowed listeners to receive broadcasts from around the world. This was a significant advancement in radio technology, as previous radios were limited to receiving local broadcasts. Belmont Radio's All-Wave radio was widely popular and helped to establish the company as a leading manufacturer of radio equipment.

In addition to its radio equipment, Belmont Radio was also known for its distinctive, high-quality speakers. The company's speakers were designed to deliver excellent sound quality and were popular with both radio enthusiasts and music lovers. Belmont Radio speakers were used in a variety of settings, including homes, businesses, and public spaces.

Unfortunately, as the radio industry evolved and new technologies emerged, Belmont Radio struggled to remain competitive. The company eventually went out of business, but its legacy lived on through its many innovations and its high-quality products. Today, Belmont Radio is remembered as a pioneering company that helped to shape the radio industry and bring the magic of radio to the masses.

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...
