Brief Specification for the Bush TR82 Broadcast RadioĮarly transistorised portable radio using superheterodyne techniques for use on the long and medium wave bands. Bush TR82 specificationsĬonsidering the Bush TR82 was one of the earlier radios to adopt transistor technology, it worked very well and many are in use today. The cost was £17 8s 11d which was quite expensive for the day, but they represented a very good radio. The initial radios launched were the TR82B and TR82C - the only difference between them was the colour scheme. The TR82 was far more convenient to use than the MB60 as it only required a single PP9 battery and this lasted very much longer than the batteries required for the valve radios. In many ways this was a transistorised version of the MB60 as it had the same case style as the MB60. However the long term goal was for a transistor radio. One of the key elements of the design was the very stylish case designed by David Ogle. Called the MB60 (MB for Mains/Battery) it was launched in 1957 was was successful. Responding to the need for portable radios, Bush initially produced a portable radio using these valves. Some low heater current and lower HT voltage valves were developed to help address this growing market, but radios still needed to use high voltage batteries (90V) as well as more powerful batteries fort he heaters. However int he 1950s there was a growing demand for portable radios. In view of the costs of early transistors and their inferior performance to valve / tube technology, it took some while for transistor radios to reach the domestic market.īush had been a manufacturer of some very successful radios for the domestic markets. The very first domestic broadcast transistor radio was launched in 1954, but in order to keep its costs down, the circuit was simplified and performance was not particularly good. With transistor technology just starting to be included domestic products a few radios started to incorporate this technology. Front view of the Bush TR82 vintage transistor portable radio Bush TR82 history The TR82 became very popular with teenagers and young people because it was portable and with people having increasing amounts of cash after the war, it sold very well. The radio was manufactured by the Bush Radio Company which had previously produced valve based favourites including the DA90 and DAC90A of the 1940s. It's style almost became synonymous with a transistor portable in the early 1960s. The Bush TR82 vintage transistor portable radio was first manufactured and became very popular.
