Paul -

Worth a shot!  :-)

Transformers that have the copper band 'shorting turn' around them typically
have a band about 1.5
- 2" wide.  I dunno if the larger cross section would help significantly or
not.  Thinking of a band the width of the core, with tabs to fit under the
transformer mounting bolts. ??

Have you tried a piece of steel, (tin can, etc.,) as a shield just behind
the PTO?  Solidly attached to the chassis.  IF sufficient improvement to
warrant, try a piece of mu-metal in the same spot.
