That makes sense, Jay.  it would, indeed, be effective for that application.

##  are u sure ?   After looking at ur cook book recipe, and other misc notes,  I still
cant fathom 2 turns inside the 6 x cores.... with one turn  external to the cores... even with
what appears to be aprx 2 inch  spacing from the single external loop to the core stack,
providing enough Z and RS  for that freq ?   I guessed  that  perhaps  3 turns inside the core
stack and 2 external loops would have optimized the design a tad better.   But I dont have the test
gear to evaluate it.    He didnt say whether type  31 or 43 used.   My guess is type 43,   since its 
a little less forgiving when it comes to heating.   I would want the RS to be as  high as possible to 
limit CM  current.... esp with serious qro being used.
