Project Notes

Overview Every module that I develop has a complete set of documentation that you can download from this web page or from the page of the modules in production. These Project Notes include:

  • An explaination of the original circuit
  • The AM circuit design modifications and improvements
  • How to build and use the module
  • Parts list and guidance on finding parts
  • Schematics where possible

So if you are interested in one of the modules go ahead and download the Project Notes to find out more!

SSM+CEM Chips

Finding SSM and CEM chips is difficult as they have been out of production for 10-20 years. Try eBay and some of the analog and synthDIY mailing lists. The newer SSM2044 and CEM3372 chips are still available from eBay because there are still 100's in obsolete semiconductor stores.
