Hi Steve,

The spread spectrum force device was "unkind" to the fully plastic 
encapsulated buss work section.  That part also got the majority of the 
slimy silicone grease and I trashed it...  I would guess that multi 
megahertz "fine" current sharing details were never a consideration for 
these IGBTs....  Fortunately, they are so darn tough they can take just 
about anything...

Cheers,

         Terry
