EARLY TRANSISTOR HISTORY AT GENERAL ELECTRIC Dwight V. Jones – Continued
______________ Go To Jones Oral History, Page 4	The photo above is from an article by Dwight that was published in the August 1958 Radio & TV News magazine. This is one of many contributions made by Dwight to early transistor HiFi circuitry. The schematic for this preamp is shown on the left; it was reproduced in the Third, Fourth, and Fifth editions of the GE Transistor manual series. By the publication of the Sixth edition, in 1962, transistor technology had developed sufficiently such that tubes were no longer competitive, even in very high end audio systems. In the 1950s, when Dwight originally developed this preamp, transistor cost and performance factors were still prohibitive issues in the design of HiFi circuits. ______________
