Key Details & Background
- Era: It is estimated to have been released around 1957. [1, 2]
- Technology: Unlike the standard transistor models the company became famous for later on (such as the SR-F22), the SR-220E utilizes miniature vacuum tubes (typically four tubes, including a 1R5 converter tube). [1, 2]
- Manufacturer History: Standard Radio Corp. was a prominent Japanese electronics manufacturer known for its early adoption of transistor technology in the late 1950s. The company was later acquired and rebranded as Marantz Japan in the 1970s.
Because of its age and historical transition placement between tube tech and early transistors, the Muse SR-220E is considered a highly collectible piece of mid-century Japanese electronics history and can occasionally be found indexed on historical radio archiver databases like the Radiomuseum.
