Analysis and restoration of a 1960s ear vacuum tube AM-FM reflex receiver

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2004.Includes bibliographical references (leaf 59).This thesis details the analysis, restoration, and evaluation of a 1960s era vacuum tube AM-FM reflex receiver. External influences such as tax laws necessitated clever designs to minimize the use of expensive vacuum tubes in radios. The thesis work yielded a thorough description of the circuits, the successful restoration of the radio to nominal operation, and concluded with a brief evaluation of the radio's operating characteristics.by Adam J.
