Transistor Radio (Electronic Age) (1 янв 1952 г. – 1 янв 1980 г.)

Описание:

A transistor radio is a type of portable radio that uses transistor-based electronic circuitry to receive and amplify radio signals. Transistor radios became popular in the mid-20th century as a more compact and energy-efficient alternative to earlier vacuum tube radios. The development of the transistor by Bell Labs in the late 1940s revolutionized electronics by replacing bulky and power-consuming vacuum tubes with smaller, more reliable transistors.
