B-36 electrical system Q.

I've been reading 'MAGNESIUM OVERCAST - The Story of the Convair B-36', by
Dennis R Jenkins, and have been finding it absolutely fascinating. Plenty of
hard-core techno stuff, esp. powerplant, a subject near and dear to my
heart. What doesn't seem to be covered is the B-36's electrical system.
Judging from the electronic equipment fitted, I would assume this to be 28V
DC and 115V 'wild frequency' AC (B-36 seems a bit early for CSD's). My
questions a

Was there a DC and an AC generator on every engine?
Single phase or 3-phase AC?
Were rotary inverters used?
How was the aircraft's electrical system organized?
