(and quite dangerous) 

But, that brings up an intersting question.  Is there anyway to quickly
check the ratio of such a transformer from winding to winding.  We have a
simple-to-use tester at work (but probably not cheap) that we use to verify
the ratio of large power transformers (as part of a series of testing). 
Anybody know how these work?  Knowing the ratios of a transformer and
something about the original application could easily lead one to the
appropriate connections and voltages.
