Description: The Radio Trouble Finder, compiled by the staff of Radio News, originally published by the E.I. Co., New York, NY, 1926. Reproduced by Nation Builder Books, Mebane, NC, 2013. 6 x 9 paperback booklet, 48 pages. Please note this is a photocopied reproduction, not an original. The accompanying pictures have been scanned from a reproduction, not the original. With Lindsay retired (and finally able to indulge his inner juvenile delinquent), there are not many sources to get good, old vacuum radio books from. So, welcome to my bizarre little corner of the galaxy! Where what’s old is cool, and what’s new is a dastardly commie infernal device made in China. Up with good old American-made RCA Radiolas, Kent Atwaters, Crosley Cathedral Tubes, and Zenith Transoceanics, and down with Chairman Mao’s iPhone! If you’re into old-fashioned ham radio or an antique radio collector and restorer, and you’re just itching to do some trouble-shooting, then this is the book for you!
