New York: RCA Institutes Technical Press, 1937 - 1940. Magazine. About 125 pages each, identical formatting, coated paperstock throughout with numerous b&w photos, diagrams and charts. Softbound in 9x6 inch plainish printed wraps; the first two items are damp-damaged with adhesions, v.I n.4 seriously (all adhesions are parted, but in this case find slight losses of text); v.V n.1 is torn at head and tail of spine panel and front cover is dust-soiled. Handleable and legible, the six together.
Every issue in this lot has one or more featured articles on TV, from "Experimental Studio Facilities for Television" by O. B. Hanson, to "A 500-Megacycle Radio-Relay Distribution System for Television" by Kroger et al.
