Regency TR-1 transistor radio. The Regency TR-1 was the first commercially manufactured transistor radio, introduced in 1954.Despite mediocre performance, about 150,000 units were sold, due to the novelty of its small size and portability.
The all-transistor car radio was a $150 option. [51] [52] [53] The Sony TR-63, released in 1957, was the first mass-produced transistor radio, leading to the mass-market penetration of transistor radios. [54] The TR-63 went on to sell seven million units worldwide by the mid-1960s. [55]
This made Sony the first company to produce commercial transistor radios from the ground up. American company Regency had launched their Regency TR-1 transistor radio earlier in 1954, but bought the transistors from Texas Instruments. Printed circuit boards were used, which was unusual for the time. [6] [8] [3]
Following development of transistor technology, bipolar junction transistors led to the development of the transistor radio. In 1954, the Regency company introduced a pocket transistor radio, the TR-1, powered by a "standard 22.5 V Battery." In 1955, the newly formed Sony company introduced its first transistorized radio, the TR-55. [65]
Some historic car radios badged as transistorised are in reality of this type. All-transistor sets eventually replaced sets with vacuum tube after transistor technology improved and prices fell significantly. Chrysler and Philco announced an all-transistor car radio in the April 28, 1955, edition of the Wall Street Journal. [1] This Philco car ...
In January 1950, after commercial units were released, he published "A Crystal Receiver with Transistor Amplifier" in Radio and Television News, along with plans for a three-transistor radio circuit. These plans – printed four years before the Regency TR-1 (the first commercial transistor radio) – were the first time most amateur radio ...
Bush Radio reproduction of 1959 TR82 transistor portable. A design icon of the early transistor radios. The Bush TR82 transistor radio, designed by Ogle Design, and launched in 1959, is regarded as an icon of early radio design. Although the first radio to use the Ogle cabinet design was actually the MB60, a battery/mains valve set from 1957 to ...
