Zurück zum Zitat Andrew Wylie, in an e-mail to Simon Lavington dated 1 Mar 2009, said: ‘The OC72 is first mentioned in Wireless World in the issue for December 1955, in a construction article, so at that time it was more than just a laboratory type. It then appears several times in 1956. This certainly suggests that it was commercially available in late 1955. Note that Mullard’s OC70 and OC71 junction transistors were available from mid-1954 onwards’. For more on the history of transistors, see Andrew’s interesting website: http://ourworld.compuserve.com/homepages/Andrew_Wylie/semics.htm from which the following additional facts are taken. The OC series was very widely used in Europe for a period of almost twenty years and many millions were made…. Mullard produced the first true high-power transistor in Europe, the OC16, in about 1956, which was capable of handling about 24 watts. The early OC series were AF (audio frequency) devices whose switching properties limited their use in high-speed computing circuits.
