It isn't a voltage doubler at all if I understand it right.  As Shaun
explains it, it uses two seperate rectifiers, creating a negative
supply and a positive one.  Both of those supplies in series create
the total difference.  This allowed us to get 7kv from one microwave
transformer.  While it oscillated in a Tesla Coil tank circuit as it was
supposed too, the arcs of the spark gap pulled too much current
killing the diodes after a few seconds.  Several diodes in parrallel
should fix this.
