TLDR: Where can I find the service manual for the Rodgers Exeter 770 pipe organ?
I am trying to repair a Rodgers Exeter 770 digital pipe organ, however, I do not have the service manual. I easily found online copies of the owner's manual (like this one), but it does not contain any of the schematics or wiring diagrams-which I need.
It has been over 3 weeks ago since I emailed and called Rodgers Instruments (the company which made the organ) asking for a copy, but I have not heard back.
If there is a Stack Exchange site better suited for this question, let me know, and I'll post there.
