In this gallery, we celebrate the Depression Era home radio, the one device responsible for keeping the sanity of a nation through almost two decades of financial despair and world turmoil.Philco Model 87 radio was an early set designed for exclusively 110 volt AC operation.Cabinet restoration Click Here To see a short video of the completed set in operation, click here While Dr.Lee De Forest was credited with the discovery or invention of the vacuum tube, court testimony in later patent infringement cases determined that De Forest did not totally understand the operation of his own invention.A classic example of an Atwater-Kent Model 84 "cathedral" radio from the height of the Great Depression.There were many manufacturers of Depression era "cathedral" and "tomb-stone" radios, however the biggest players in the market place by far, during the 1930s, were Atwater-Kent, Philco, Crosley and Zenith.
Armstrong began to employ De Forest's discovery in the construction of practical radio receiving apparatus.
The Model 84 was Atwater-Kent's offering to compete with the popular Philco 70 and 90 series sets.
The Philco Farm Radio was a basic superhetrodyne circuit similar to the Model 70, however, like its 1920's predecessors, it was designed to operate on storage batteries for service in rural areas where commercial electricity was not available.
This beautiful example was only recently acquired by the Museum Of Yesterday, and is a proud addition to our collection.
Shown below, the rear of the set illustrates the simple array of components that set the stage for the design of most table radios built before World War II.
