        I've got a tesla coil that I'm fixing up for work and am having
a
little difficulty with the terminal. It originally had a Al sphere about
12" in diameter and I want to switch over to a toroid design. I'm
wondering how I decide the correct size of the toroid given my
components. Here are the specs on my current system.

        15,000 V transformer
        15 pf capacitor
        12" diameter 14 turn primary
        5" diameter, 36" length secondary

        I think that covers the specs. If anyone has any ideas on how
big
a toriod I can construct, please let me know. Thanks.
