DescriptionThis is a series of lantern slides from E.L. Chaffee's lectures, in a bright green, canvas-covered wood box with a brass snap enclosure. They are primarily on topics such as power tubes ca. 1930's-40's and regeneration coupled circuit matching. An early researcher in the theory of vacuum tubes, Chaffee published many papers in electronics, physics, and biophysics, and also lectured extensively on these topics.
