	The rectifier in such a system must withstand twice the peak voltage of
the coil without breakdown, so the spacing would have to be very wide. 
I have no doubt that rectification would take place and the general
consensus that the well known residual charge on varnished TC's is due
to recification by dissimilar terminals.
