Gary: You have said the size of your capacitor, but nothing agout your coil
size. The secondary coil sets your frequency. The primary is adjusted with
your capacitor to match your secandary frequency. With no information about
your coil size no one can help you. What frequency are you working with ?
The lower your frequency is the larger the capacitor you can use. The higher
your frequency the smaller the capacitor you can use.
