I too, wish to connect a PR40, but to an M3.
I have a 26-1 connector and a 6-pin cable (same kit and cable for a Leslie 145), and was wondering what to do next. I too have seen many schematics for Leslie connectvity, but none for PR40s.
When I finish, will I have the option of connecting either a Leslie 145 or the PR40 to the same box, or are they wired specifically for only one or the other?
Two wrongs don't make a right, but three rights do make a left.
