Braun T1000 receiver

Braun T1000

Braun T1000
Introduced in 1962 at the Berlin Radio Fair, this has become an iconic Dieter Rams / Braun design and part of the permanent collection of the Museum of Modern Art in New York. It was just recently that I was lucky to acquire this excellent condition T1000 AM, FM, LW, short-wave radio with internal PSU TN 1000 AC adaptor.
