A big you're welcome to all who commented and again thanks to Bill for posting these. I also sent in some more pics, of the projection equipment and old motor-generator there which is also still fully operational.
As I'd mentioned in part 1, those contactors are the main source of trouble there. And so far, neither the building maint. super nor I have been able to locate any kind of spares or source for replacement parts. The current line of thinking is that they'll have to somehow adapt modern open contactors to repalce the ones that failed.
As techie mentioned, to de-energize this would take out (in this case) the entire booth [lights too!] and a good portion of the mezzanine level. I guess sparkies back then worked things hot a lot more than we do today. (Of course, we tend to survive longer now too.)
