AMRAD Radio: A Brief Overview and Historical Context
Amrad, American Radio & Research Corporation, was based in Medford Hillside,
Massachusetts and was founded in 1915 with funds from J. Pierpont Morgan. The company's
first manager, Harold James Power, was an amateur radio enthusiast and built a research
laboratory. In 1916, Amrad made its first broadcast to J. Pierpont Morgan Jr., who
was aboard the ocean liner "Philadelphia."
Amrad received orders for military radio equipment during World War I, but discontinued
these orders after the war ended. To keep the company afloat, Amrad produced items
such as electric egg beaters and cigar lighters. In 1919, Amrad was awarded a contract
to make 400 SE1420 receivers, and it began advertising components for amateur radio
enthusiasts. Amrad's crystal set was a popular product and helped the company during
In 1923, the company joined the Independent Radio Manufacturers Inc. and acquired
the rights to the Hazeltine neutrodyne invention. However, Amrad went into receivership
in April 1925 and was purchased by Crosley Radio Corp. for $39,000. Amrad also made
gaseous rectifier tubes, including the S tube developed by Charles Grover Smith,
which was used for transmitter voltage. Amrad's patents for the gaseous rectifier
tubes were eventually sold to Raytheon.
Arvin Radio: A Brief Overview and Historical Context
Arvin, brand of
Noblitt-Sparks Industries, was a brand of car radios and audio equipment that
was popular in the 20th century. Founded in the 1930s, Arvin quickly established
itself as a leader in the field of automotive sound systems. Known for its quality
and reliability, Arvin's products were widely used by American consumers and became
synonymous with in-car entertainment.
At a time when radio was still a relatively new technology, Arvin's car radios
stood out for their compact size and ease of use. They were well-designed and offered
a range of features, including AM/FM tuning, volume control, and push-button tuning.
Arvin also offered a range of other audio products, including home radios and portable
speakers, that were well-received by consumers.
Over the years, Arvin continued to evolve and innovate, adding new features and
keeping up with changing trends and technologies. The company's products were widely
available through a network of dealers and distributors, and they were often featured
in advertising and promotions aimed at the American public.
Despite its early success and popularity, however, Arvin faced increased competition
in the latter half of the 20th century. New technologies, such as cassette tapes
and CD players, emerged and changed the way people listened to music in their cars.
Additionally, foreign brands entered the market and offered products that were more
advanced and less expensive than Arvin's offerings.
Despite these challenges, Arvin remained a significant player in the automotive
audio market for many years. However, as the company faced financial difficulties
in the latter part of the 20th century, it was eventually acquired by another company
and the Arvin brand was discontinued.
Today, Arvin is remembered as a pioneering brand in the field of automotive audio.
Despite the challenges it faced and its eventual decline, its legacy continues to
influence the industry and is still celebrated by many people who remember its products
and the role they played in shaping the American automotive landscape.

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.
