HAM RADIO REVIEW: COLLINS 75A-4 RECEIVER QST April 1955, ads: Heathkit, NATIONAL

Description

Up for auction is a vintage issue of the April 1955 QST magazine.
Of particular interest is a review of the Collins 75A-4 receiver. This is a four-page article for this classic radio. It describes the circuitry used in the 75A-4 radio, some unique new features (compared to previous 75 models). A block diagram and partial circuitry is also included in this article.
Please check the table of contents for a list of other interesting articles and regular features.
Overall, this magazine is in very good condition, with very light cover wear and no tears, marks or missing pages.
Also of interest are many ads from manufactures, some no longer in business. They include Collins, E.F. Johnson, Heathkit, International Crystal, Lafayette Radio, National, Hallicrafters, Harrison Radio, Henry Radio, Radio Shack (when they were based in Boston), Hammarlund, Walter Ash, etc.
