Sencor

Sencor sold many radios in Europe during the 1970's and 1980's. The brand name was created in 1969 by Celtone, an Aiwa distributor in Japan. But it is unknown who actually manufactured the products. They were definitely made somewhere in Asia, but there were other employees in Europe who handled the design work and the sales and marketing. Some of their radios have a badge that says "Designed in Switzerland, Made in Japan".

Currently they are headquartered in the Czech Republic. You can read about them here: http://www.sencor.eu/brand-sencor
They sell everything from TV's to toasters to MP3 players. Philips is their main competitor now.
