Atwater Kent Factory Service Manuals Atwater-Kent Factory Service Manuals:
These are factory service manuals with schematics scanned in high resolution directly from the original Atwater-Kent Service Manuals. All files available below have a brief description of some of the service information available in the file. View the list below of Atwater-Kent models and pricing on each individual factory service file. To order click on the "Add To Cart" button.
If your model is not listed below you can also check the
Atwater Kent basic schematics page for schematics for additional Atwater Kent models.
It normally takes up to 24 hours to receive the download instructions via email but please allow 1 - 2 business days.


IMPORTANT NOTE: Although Atwater-Kent provided schematics and wiring diagrams in it's early service files, most components were only listed on the schematics as Atwater-Kent part numbers or module types. This might have been to prevent radio shops from using non-Atwater Kent parts. However, I provide a free 24 page A-K parts list with any 1924-1932 file purchased below as a download to assist in identifying the values of the components listed in these original early Atwater Kent service files.

* IMPORTANT NOTE: Although Atwater-Kent provided schematics and wiring diagrams in it's early service files, most components were only listed on the schematics as Atwater-Kent part numbers or module types. This might have been to prevent radio shops from using non-Atwater Kent parts. However, I provide a free 24 page A-K parts list with any 1924-1932 file purchased above as a free download to assist in identifying the resistors and condensers listed in these original 1924-1932 Atwater Kent service files.

Schematics offered here are digitized in high resolution from the original Atwater-Kent factory service documents. I stock over 300,000 schematics for hundreds of radio manufacturers. Each radio schematic is digitized individually and checked to provide the clearest diagram possible from the original printing.

The data and files offered here are from vintage sources that are no longer published. There is no guarantee of the accuracy of any information offered. It is solely up to the end user to decide that the information and files offered here are accurate and fit for use with their equipment. I am not responsible for any loss or damages that may be incurred from the use of this information.
