Thanks Mike for the reply.  What is the reason they pot them in the
first place?  Dennis

Hi Dennis,
   They pot them for one main reason....to make them weather 
proof.   The secondary benefit is that no corona will be developed in 
the tar, which might lead to early failure of the transformer.  When 
we play with them,  we tend to exceed their design limitations, so 
sometimes a carbon track will form and essentiall short out one side 
of the transformer..  Some have had to remove a layer or two of 
windings in some cases because they created a short between 
layers,  but I think that is a rare occurance.
Mike
