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.

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 255 Radio Service Data Sheets as of April 30, 2025.
