Hello,
Redrawing SDS9 schematics took me a lot of time (some months with paper,pencil,digital multimeter to trace connexion.....)
I will be happy to see original SDS9 schematics from simmons....
See you soon

  I have both original and Thierry's. I can tell you Thierry's are the accurate drawings. There are errors in the original Simmons schematics. I have repaired many SDS9's so I speak from experience.
