The speaker grille was made from punched aluminum, and its design was reportedly inspired by Lincoln Motor Company automobiles of the era. Printed circuit boards were used, which was unusual for the time. American company Regency had launched their Regency TR-1 transistor radio earlier in 1954, but bought the transistors from Texas Instruments. This made Sony the first company to produce commercial transistor radios from the ground up. The TR-55's five transistors were designed in house by Sony, the technology having been licensed from Bell Labs. The TR-55 used the following transistors: ![]() Powered by four AA batteries, the TR-55 used a superheterodyne circuit incorporating two AF stages and covered the medium wave broadcast band. ![]() ![]() The TR-63 would not fit in existing shirt front pockets, so the company issued shirts with expanded pockets to salesmen so they could claim the product was "the world's first pocket sized transistor radio". Sony later signed a deal with New York importer Adolph Gross to distribute an improved and slightly more compact model, and in March 1957, the Sony TR-63 transistor radio would become Sony's first product sold in the US.

The first model was called TR-52, but was pulled from the market before it had even been introduced after climbing summer temperatures made the front lattice section to gradually peel away from the black cabinet, forcing the company to build a new model using a more durable material. The use of transistors allowed the device to be much smaller than earlier vacuum tube radios.Īkio Morita and Masaru Ibuka, then operating under the business name Tokyo Tsushin Kogyo, had been working on plans to introduce a transistor radio to the market since 1953. The TR-55, released in 1955, was both Japan's and Sony's first commercially available transistor radio.
