Hello Everyone,


Philco was a "Powerhouse" in the 1950's, as far as its Transistor research and consumer product development. It produced many "World First" consumer products during this period ....

For example...

1953- World's First High-Frequency Transistor used for computers (Surface-Barrier Transistors)
1955- World's First Transistor car radio (model C-5690)
1955- World's First Transistor portable battery operated Phonograph (models TPA-1, TPA-2)
1957- World's First Transistor Large scale Commercial Computer (Transac S-1000)
1959- World's First Transistor portable battery operated TV (Safari)


Below is an article that I found in the Motor Life December 1955 issue, which shows the 1956 Chrysler Imperial that had an "optional" All-Transistor Car radio available. This car radio was manufactured by Philco (model C-5690) and was the "World's First All-Transistor car radio to be developed and produced.
