June 1936 Radio-Craft Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Craft, published 1929 - 1953. All copyrights are hereby acknowledged.

Atwater Kent Model 776 Automobile Radio - RF CafeThis thumbnail image of a Atwater Kent Model 776 Automobile Radio is from the AtwaterKentRadio.com website. You can see from the picture that the entire radio was contained in a single chassis, unlike many models of the day that had the bulky RF electronics mounted behind the dashboard or under a seat, and the listener interface controls mounted separately in the dashboard. Below is the Radio Service Data Sheet as it appeared in a 1936 issue of Radio-Craft magazine. It was one of six such documents that appeared - without any description or alignment information included as is normal with the individual, full page data sheets.

In early sets, the upper of V4 is 5,000 ohms with a voltage drop of4 V. and the lower is 15,000 ohms with a drop of 10 V. In late sets, as shown, resistors   are 10,000 ohms each, with a total drop of 12 V. Early sets also had a 0.1-meg. plate resistor for V4 with a drop of 55 V., making plate voltage 125 V. Voltage is much lower with the 0.25-meg. resistor shown. Early models do not have a tone control and the "A" filter circuit is slightly different than shown.· The bypass condenser on the pilot light is 0.2-mf.

Arthur Atwater Kent: A Biography

Arthur Atwater Kent (wikipedia image) - RF CafeAtwater Kent was an American inventor, entrepreneur and manufacturer of radio equipment. He was born on December 12, 1873, in Cassopolis, Michigan and died on August 30, 1949, in Philadelphia, Pennsylvania. He was a pioneer in the development of radio technology and his impact on the industry is still felt today.

Kent began his career as an electrical engineer, working for various companies before starting his own business in 1918. He founded the Atwater Kent Manufacturing Company in Philadelphia, Pennsylvania, with the goal of producing high-quality radio sets for the public. The company quickly became one of the largest radio manufacturers in the United States, producing over one million radio sets between the 1920s and 1930s.

One of Kent's innovations was the development of the "breadboard" radio set, which was easy to assemble and repair. He also made use of more efficient components, such as high-voltage power supplies, which allowed his radio sets to produce better sound quality. His radios were also known for their beautiful wooden cabinets, which were handcrafted and came in a variety of styles and finishes to suit any decor.

Atwater Kent was a visionary who understood the potential of radio as a means of communication and entertainment. He was an advocate for the development of commercial radio broadcasting and he supported the establishment of the National Broadcasting Company (NBC) in 1926. This network helped to bring radio to a wider audience and it was a major factor in the growth of the radio industry.

In addition to his contributions to the radio industry, Kent was also a philanthropist. He supported a number of educational and scientific organizations, including the Franklin Institute, and he established the Atwater Kent Foundation, which provided grants for scientific research.

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.
