CarryCom Portable Component System CK-R11

The "CK Series" was a group of mini stereo components (and speakers) made by Pioneer. They're from around 1983, as that's the date on the service manual. They were some of the best-sounding portable systems of that era.

Collectors often refer to the advertised models as the CK-3, CK-5, CK-7, or CK-11, but it's a bit more complicated than that, because people could mix and match quite a few different components to create their own custom set. See attached spec sheets detailing some of the options.
