The first book of its kind, the 1933 Official Audio-Radio Service Manual contains all the auto-radio service data available on July 5, 1933, the original publication date of this book. It is a complete director of all automobile radio receivers and presents full installation and trouble-shooting guides. A few manufacturers are not represented because they had no information ready for release at that date. Receivers made by companies including Acme Radio, Allied Radio, Arvin, Atwaterkent; and on through Galvin, A. H. Green, Grigsby-Grunow; and on through Philco, Transformer Corp of America; and concluding with Rudolph Wurlitzer and Zenith are just a sampling of the brands covered in this single comprehensive volume. The origina manual was assembled in loose-leaf form. Its pages were 3-hole punched and came bound in a fabric covered volume. We have brought back the original material for those who still own or collect these old receivers and have been looking for comprehensive service data.
