The BUSH DAC90A Radio was introduced in 1950 and was made until about 1957 and is one of the most collectible post-war radios. This one in brown is a later model, the style of the knobs with gold trim indicates that it is a late model. A good condition brown DAC90A would be worth up to £75.
Bush rose from the ashes of Amplion who made speakers for British Gaumont cinemas and thus had links with the film industry.The radios were advertised in Gaumont cinema foyers as "A Gaumont British Product". Murphy experienced problems keeping at the forefront of technology and lost creditability with their dealers, many of which changed over to Bush. At some point Murphy became part of Bush and the company trade as Bush - Murphy in Chiswick, London. In 1945 because of their links to the film industry, Bush Murphy became part of the Rank empire and changed the name to Rank Bush Murphy (RBM). A new satellite factory was opened in Plymouth in 1949. During the mid 70's (When they were one of my major customers! I worked then for RCA Solid State having previously been with both Mullard & STC) ) they moved the entire operation to Plymouth. In 1972 the name was changed again to Rank Radio International (RRI). Following several years of mounting losses they tied up with the Japanese to become Rank Toshiba in 1978. This lasted just 3 years, and in 1981 finally folded. Toshiba became sole owner of the Plymouth factory. The Bush name now belongs (along with Alba) to an importers in Barking, E London.
