Scope and Content
Process files contain rough drafts of tube specification publications, comments on drafts made by RCA scientists and executives, correspondence between RCA and Electronic Industries Association (EIA) staff, as well as technical data and other materials related to the writing and publication of the tube specifications.
In addition to their type numbers, some folder labels feature the abbreviation “Comm. Eng.
