Re: transformer question

Just to be sure you (and Reinhard!!) get it, I am talking about LEAVING
THE CASES UNGROUNDED. Just from a hypothetical, and not neccesarily
practical, point of view. If the primaries are in series, then there
would be no extra stress on the insulation for the seriesed secondaries,
as the total volatge would be equal to that of one original transformer.
...and the current would be doubled, would it not?

	What you will probably end up with is shorts between the center of the
transformers and the primary.  The insulation there just was never
designed to handle that voltage.  Might last for a while and might not. 
Anyhow, even if it did work, the thought of those floating secondaries
is frightening.
