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 ...
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.
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.
The rocket radio was also used as an emergency radio, because it did not require batteries or an AC outlet. The rocket radio was available in several rocket styles, as well as other styles that featured the same basic circuit. [38] Transistor radios had become available at the time, but were expensive. Once those radios dropped in price, the ...
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]
1954: Regency introduced a pocket transistor radio, the TR-1, powered by a "standard 22.5V Battery". 1960: Sony introduced their first transistorized radio, small enough to fit in a vest pocket, and able to be powered by a small battery. It was durable, because there were no tubes to burn out.
