Rather similar to previous thought using inductive coupling to primary with
Make similar coil to couple to primary ie few turns of Cu tube on insulating
sheet Add sufficient Capacitance to actually tune this to Fp. Place a
resistive load across this tuned cct and place above the primary coil. .I
suspect load in series with the L and C would be fine too.

This arrangement
*Avoids big HV secondary spikes in the lab.
* Avoids having to change wiring in the primary cct to provide dummy load.
*  Is a reasonable look alike for a true secondary in terms of coupling
interaction but does have a constant load ie no streamer laod at breakout
*  If the load is a lamp (or series of lamps) can be used to check Max O/P
by adjusting for max brightness.
