Hi Jason ...

I too had a similar problem with wires in the primary side ...   I went
to a smaller dia wire with thinner insulation ...  I eventually found
that the thinner insulation was allowing the primary wire set to arc to
the case ...

results  ...  loss of alot of power in the primary side   very little
streamers  ( 8" from the 24" previous) 


check the primary wires for touching the case/stand assy.    it makes a
difference..
