Sony STR 5800 stereo receiver. Classic Vintage. Fully revitalized.
The company was established by Masaru Ibuka and Akio Morita in Tokyo in 1946 as Tokyo Tsushin Kenkyu-jo Research Institute, initialy providing service. A year later, it was transformed into a company called Tokyo Tsushin Kogyo Kabushiki Kaisha (abbreviated Totsuko), whose main purpose was the production of telecommunications equipment and voltmeters. The 50’s turned out to be crucial for the company. At that time, a tape recorder and transistor radio were created, and in 1955 a decision was made to use the SONY logo on Totsuko products. The name came from the Latin word “sonus” – sound and “sonny boy” – used in the US to describe a little boy. The 1960s were a period of rapid development and international expansion for the company. Then also TA-1120 was created, which is the world’s first stereo receiver based on silicon transistors. In 1979, the iconic SONY product appeared on the market, a portable “walkman” cassette player. In the following decades, the company also introduced and promoted trademarks such as discman, trinitron and playstation.
The company’s rapid growth has boosted sales and reputation. In 1960, the decision was made to open the first foreign branches in the USA and Switzerland, making Sony become a true international corporation.
The STR series is one of the largest commercial hits in the history of the Japanese company, at least when it comes to the audio equipment market. Many lucky owners say that these receivers work exactly like forty years ago. The tuner itself was obviously not created as an additional gadget, but as a very good quality radio receiver (which works also with an ordinary wire).
