Collaborating what Gary said, the folks on the Organ Forum have pointed out that the caps in question were not polar, and won't work with polar caps.

They also pointed out that the circuit I drew makes no sense. I agree, but don't know much. I double checked the schematic and it is correct, and the circuit is as I found it upon purchasing the organ, and it did run. I have no clue how it works, just that it does.
