Hello Matthew
I tryied to keep the maximum distance between the
coils (secondaries and primary, to prevent the
possibility of breakdown). maibe I can try something
like that:

          SSSSS           SSSSS
          SSSSS           SSSSS
    CCCCCCSSSSSCCCCC--CCCCSSSSSCCCCCC
    CC    SSSSS           SSSSS    CC
    CC    SSSSS           SSSSS    CC
    CC                             CC
    CC                             CC
    CC                             CC
    CC    PPPP  FF                 CC
    CCCCCCPPPPCCFFCC--CCCCCCCCCCCCCCC
          PPPP  FF

 The upper crros member is removed and then the two
U-shapped ferrite cores are tight mounted end to end.
 I tryed to not dismantle the flybacks. in this way
the mountage is very easy to make, in a short time.
