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]
The success of transistor radios led to transistors replacing vacuum tubes as the dominant electronic technology in the late 1950s. [28] The transistor radio went on to become the most popular electronic communication device of the 1960s and 1970s. Billions of transistor radios are estimated to have been sold worldwide between the 1950s and ...
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.
Their first product was a vacuum tube radio released in 1955, [3] [4] and their first transistor radio was the KR-6TS-1 radio released in the spring of 1957 [5] [6] at the price of 14,000 yen. [7] Through the 1960s, Koyo had manufactured and sold millions of portable transistor radios, particularly, their best-selling model KTR-624 had been ...
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.
Another first for portable radios was the unique dial scale used in the 1000 and later series of Trans-Oceanics. The 1000 was designed with a cylinder dial scale that would rotate with the band switch allowing only that particular band scale to show. [9] Zenith Royal 1000 All Transistor Trans-Oceanic Short Wave Portable Radio, circa 1957.
Later transistor-based AC table radios typically used power transformers and operate safely, but with likely hum from failed electrolytic capacitors in the power supply, and likely low volume from other failed electrolytic coupling capacitors. There were a few early transistor table radios using "hot chassis" principles, but these are very rare.
