The first commercial transistor was, without a doubt (IMHO) made by Regency. It's sensitivity was such that it could pick up the more powerful local stations most of the time. It used a 22.5 volt battery. Hit the market ca. 1957, and cost about $55. To the best of my memory, Isaac isw@cup.portal.com
