Brand: Toshiba
The Toshiba SA-520 is an electronic product, specifically a compact audio cassette player or tape recorder, released by Toshiba in 1979 (or possibly 1980, as some sources suggest). Its designation "SA-520" is likely an internal model number assigned by the manufacturer for production and inventory purposes. As the model number indicates, this device belonged to Toshiba's SA series of audio products, part of a range that included tape recorders, stereo systems, and other audio-related devices. The SA-520 featured a playback capacity of one hour on one standard audio cassette tape and offered built-in speaker functionality for convenient audio enjoyment without the need for external speakers. It's possible that the device incorporated various advanced technologies for Toshiba, such as Dolby noise reduction, automatic tuning, or quick-start features, given that Toshiba was a pioneer in audio technology and a key innovator in the cassette tape market of the time. However, without detailed specifications or documentation, it's difficult to know for certain.
