David,

Generally, you want the extra coil to have a lot more inductance
than the driver.  this keeps the voltage at the top of the driver
lower, and prevents flashover.  In one of my magnifiers, I used
7mH in the driver secondary, and 30mH in the extra coil.
Generally they won't work as well if they're calc'd to be at teh
same frequency.
