Radio Rim
Radio RIM , actually Radio-Industrie-GmbH Munich , was a shipper of electronic components and a manufacturer of electronic assemblies and devices. For decades, the headquarters were located opposite Munich Central Station at Bayerstraße 25. The products were mostly sold in kit form, including by mail .
The company was founded in 1922 under the names Ezetka-Industrie GmbH and Radiola-Industrie-GmbH and renamed Radio-Industrie München (RIM) in 1925. In 1991 it was taken over by Conrad Electronic , Hirschau . The very angled main building at the main train station was subsequently closed.
Radio Rim was known for the electronic handicraft yearbooks that had been published since 1925. The yearbooks were much more than a mail order catalog for kits , finished devices and components; they should convey modern electronics to the readers in a “solid, professional manner, both in terms of technology and the electronics market” (RIM-Jahrbuch 1989). The circuit diagrams from our own development laboratory were published with the kits . The yearbook has been required reading for generations of engineers and amateur electronics enthusiasts.
Well-known device series from Radio Rim were the organist , a mono mixer amplifier for sound reinforcement purposes or the Gigant mono power amplifier . In the 1950s, a kit for a tape recorder called the Rimavox was even produced.
