November 1946 Radio News

November 1946 Radio & Television News Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

The Belmont model 5D128 was a compact, inexpensive tabletop AM radio set. A schematic and parts list for it appeared in the November 1946 issue of Radio News 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, so I scan and post them whenever they appear in magazines which I own (almost never from an online PDF, unless I need some support information). While researching the Belmont 5D128 tabletop radio, I ran across an excellent video created by Mr. Paul Carlson (see below - note how the setting looks like he's in the International Space Station), as part of his Mr. Carlson's Lab series. Here is a great video of Mr. Carlson troubleshooting an intermittent noise problem in a receiver. That "Carlson RF SuperProbe" he is using looks like a must-have piece of test equipment! Click on the link for another video showing how to make it. The Classic Radio Gallery page on the Belmont 5D128 shows magazine advertisements from other companies such as Airline (Montgomery Ward), Coronado, Lafayette, Good Year, which rebranded the exact same radio with their own names.

Belmont Radio Corporation logo - RF CafeBelmont 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.
