This is a well working Blaupunkt car radio with Stereo FM, medium wave and long wave. The Stockholm 21 Stereo has a strong amplifier of 2x10 watts and a nice sound. Everything works well, the radio, the knobs, the stereo reception. The cassette player also functions, as well as the lighting. Remarkable is the presence of loudness, Dolby noise suppression and 4 loudspeaker connections. This nearly 40-year-old radio cassette player was one of the better Blaupunkt radios in the early 1980s and was used as an option in Porsche, Volkswagen, BMW, Opel and Audi cars from the 80s Characteristics: - type: Blaupunkt Stockholm 21 cr 7641047. - AM, long wave and FM - Manufacturing year 1981 - Stereo - loudness - Dolby noise suppression - 2x10 watts output power - 4 connections (stereo) for speakers - connection for (electric) antenna - Radio dimensions (w x h x d) 179 x 45 x 160 mm - front dimensions (w x h) 185 x 60 mm - Made in Germany
