Think of the primary circuit as capacitor, spark gap, primary coil in
series.  The difference is whether you charge the capacitor directly (i.e.
hook transformer across cap) or charge it through the primary (transformer
across gap).. The primary impedance is so low at power line frequencies that
it might as well not be there, so performance wise it should be the same.

I hooked my transformer across the gap.  Why?
1) The gap acts to limit the voltage seen by the transformer (so that it
essentially clips any HV transients that might creep back)
2) I can set the gap with the cap and primary disconnected (by removing the
tuning clip).
