Free Downloads

     In addition to collection radios, I have a large library of early service information, books, manuals, magazines, and advertisements. I have scanned a few documents and made them available for free download. While a majority of these documents are scanned by me personally, a few are scanned by others and no longer available online, so I re-posted them here with the proper credit given. If you have anything that you would like to contribute, please contact me with your info.

    You can view the downloads by clicking the links, and view/print from your browser. If you would like to save the files to your PC, right click the links and select "Save Target As", and save to your PC.

  Unless otherwise noted, all of these scanned documents are property of me, Jeremy Schotter. I made them available online, free to download, as a service to other collectors and restorers. For more sources of free manuals, books, schematics, and other technical data, please visit the below links.
