Description
SANYO RD 4600 cassette tape recorder. DOLBY SYSTEM. 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 RD 4600 cassette tape recorder with Dolby system is the top SANYO model from the first half of the 70s, which was dubbed luxury audio equipment. It was designed as part of high-quality stereo sets. A direct drive with a brushless, low-speed DC motor with a magnetic core guaranteed the best synchronous sound. Other characteristic features include separate control of the input and output levels channel, a three-stage switch: CrO2, LOW NOISE or STANDARD and the Dolby N.R. system. In addition, the RD 4600 is distinguished by a beautiful simple form and an adjustable desktop with recording and playback levels.
The enclosure has been completely revitalized, made of American walnut wood; new, thicker side boards create an exceptionally refined and sophisticated look.
Additionally, a new red illumination of the front panel has been installed.
The recorder has been fully reviewed and serviced.
