To Bob (?)
The goal is not to drop the voltage, but to limit the current; it's different.
You do want the full voltage, or near to it, but current must be limited.

Let us know what's happening with your TC.  The most common problems
are poor tuning (maybe due to not enough primary turns), and poor spark
gaps, such as pointy needle gaps.  Are you getting any spark output?
