Not sure if this is a Dieter Rams design, but regardless, I love this 1970s Braun Audio 400S hi-fi system on eBay.
It has the ‘Rams’ look about it, cool understated modernism and a design that really hasn’t dated. In fact, technology aside, this is very ‘now’.
It dates from the mid to late 1970s and is described as being in ‘excellent condition’, having been in the care of its first owner since purchase. It still offers record playback at 33 and 45rpm, as well as radio reception over four bands. It doesn’t have the speakers though – you’ll have to source some speakers with DIN plugs elsewhere.
Note that it comes from Germany, so will need an adaptor to use. But also note that this currently at just 97p with no reserve.
