Jeff,

The primary tank of a magnifier tunes to a combo of the extra coil and
the secondary.  In other words, the extra coil and secondary act as
sort of one coil together in a sense (although the L will be less than
one big combined coil because the two coils are separate).
Bottom line is that the the primary tank must be tuned to a lower
frequency than the 1/4 wave resonant freq of the extra coil.  Yes,
the topload would be in place while you tune the coil by tapping
along the primary as in any normal TC.  A magnifier is basically
the same as a normal TC in most aspects.
