I was on the phone last night with another friend well-connected to this place and he said that the wiring *to* the chandeliers is in excellent condition. There is a grouping of six switches in a back area: one dimmer for the four corner chandeliers, two dimmers for each of two larger chandeliers (four total) and then three SPST for the central chandelier, reduced from eight (which I am still having trouble grasping). All of this is in conduit, I believe.

I don't know where the dimmers for the large banquet lamps are, but there must be a series of dimmer controlled receptacles for the room.
