An early 2000s transistor radio (Sony Walkman SRF-S84 transistor radio, released 2001, shown without earphones) Rock 'n roll music became popular at the same time as transistor radios. Parents found that purchasing a small transistor radio was a way for children to listen to their music without using the family tube radio.
When the TR-55 was released in Japan in August 1955, [3] it was the first transistor radio marketed in that country. The TR-55 featured the Sony name, but the company did not officially change its name to Sony until January 1958. [4]
The RCA model R7 Superette superheterodyne table radio. This is a list of notable radios, which encompasses specific models and brands of radio transmitters, receivers and transceivers, both actively manufactured and defunct, including receivers, two-way radios, citizens band radios, shortwave radios, ham radios, scanners, weather radios and airband and marine VHF radios.
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]
In the 1960s, company best seller products became transistor radio receivers. One of the most famous was the Koliber model. In 1969, three- band receiver models were available ( Dominika and Izabella ), as previous radios could only receive two bands, low frequency and medium wave , and a year later the Laura 4-band receiver came into production.
The Regency TR-1, which used Texas Instruments' NPN transistors, was the world's first commercially produced transistor radio in 1954. Size: 3×5×1.25 inch (7.6×12.7×3.2 cm) Following development of transistor technology, bipolar junction transistors led to the development of the transistor radio.
The Sony TR-63, released in 1957, was the first mass-produced transistor radio, leading to the widespread adoption of transistor radios. [44] Seven million TR-63s were sold worldwide by the mid-1960s. [45] Sony's success with transistor radios led to transistors replacing vacuum tubes as the dominant electronic technology in the late 1950s. [46]
