I finally got my Whirlpool Duet out of the bulit-in laundry closet and 
out of storage as our remodel is nearing the end.  The electronics 
inside is exactly the same as the one pictured in .... EHam article 
follow-on to mine, even though his is a Sears brand.
I checked the control board inside and the one Whirlpool sent me for 
replacement, and they are different.  But when I swapped them, there was 
no noise improvement.

I haven't swapped the front panel board yet.  It is shielded on the 
inside (box around the front panell board), but I can't tell if it is 
shielded on the front yet.  There were no internal ferrites, and the AC 
filter was roughly the same small one pictured, though different 

I have a large Sprague filter to mount internally, so big ferrites to 
put on some cables, and some smaller ones to clamp on.  I will be 
putting the rest of them together as I can, and grounding the whole 
thing to a "Ufer" ground that I had installed directly in the new 
laundry room.

So, in other words, the two worst offenders we have heard about both 
have the same electronics control board.  I will report more news at it
