how much primary ???

Hi Guys

It`s been some time since I had to work this stuff out and I`m stumped

I know most of the coil paramiters but not the primary inductance


The coil is:-

12 1/2" by 61" using 18AWG wire with a 6" by 28" top load the frequency is 64.73 KHz
I`m using 0.02 uF of primary cap.

So how much inductance do I need on the primary to get the system to tune.

I`v used a few PC programs but the figures are out of there range.
