In the old days, though, diodes in solid-state form did not exist (at least not in a form that would work in organ keying circuits), and so the folks had to depend instead upon multiple contacts. If your Great manual operated 5 couplers, then you had to have 5 (or 6) contacts per Great key. If you had a large unit organ, then you needed a relay that might operate 100 contacts per key (San Francisco Fox Wurlitzer Great: 92 contacts). From each and every contact ran a wire to a position on a coupler or stop gang switch, quite a bundle for a large instrument (SF Fox Great: 92 * 61 =3D 5612 conductors).   My first theatre organ job consisted of wiring the added stop switchs to a Wurlitzer relay; that cable had "only" about 700 conductors, all white, of course, each one of which had to be "rung out" with a buzzer and then routed to the proper location. Modern-day solid-state relays = (computerized or not) take away all that "fun"!   Larry Chace

I have been working on my organ project at = =3D home this weekend and have made great progress.

Turn them over =3D and retighten and see what happens. My pedal board is an old Hinners =3D (1922) and they were notorious for light actions, not anymore. =3D20   Good luck on your projects!
