I wish it was that easy, but as mine is an SSTC, I don't think that 
holds... I'm still trying to understand the relationship between primary 
& driver and secondary voltage/current in an SSTC.

I hooked up a power supply with both variable voltage and variable current, so I can easily 
control and monitor both in the primary circuit. Sadly, this doesn't seem 
to create a reliable change in the output (other than sparks getting 
shorter as primary voltage goes down).
