Phil,After double checking everything, below is my most recent JavaTC output file. These numbers are based on a 6.0" diameter secondary. This is the worst scenario yet, with a Primary Resonant Frequency of 0 KHz. What in the world did I do now?
I look forward to you comments.

Frequency
Tim, A secondary giving 82khz implies an 8 or 10 inch diameter, but a primary that is wound to fit around a secondary that size, would I imagine have a lower freq than 164 kHz, unless of course you're using very few turns. Check the dimensions that you entered and what JavaTC gives you, and postthe JavaTC output file (use the "Format Design as text" button, then selectand copy, and paste into your email.)

Frequency Thanks Phil, The numbers from my first try on Java didn't look right. The calculated primary resonant frequency was 82.81 KHz and the secondary was 164.75 KHz. The HV power supply will be a 14,400v PT. I'm not sure how I got so far off, but will modify some of the main parameters. Any suggestions will be appreciated. Keep in mind you will be trying to explain things to a Mech. Eng. Thanks again, Tim Flood -------------------------------------------------- From: "Phil Tuck" <phil@xxxxxxxxxxx> Sent: Monday, June 17, 2013 4:18 PM To: "'Tesla Coil Mailing List'" <tesla@xxxxxxxxxx> Subject: RE: [TCML] Primary/Sec. FrequencyTim, You want the primary frequency a little under the secondary frequency, maybe 3 to 4 % on a small coil. The reason is the streamers on the toroid havecapacitance and when the streamers form, they drop the secondary frequency down a little bit. So by tuning the primary low to start with, they shouldhopefully end up both about the same.

Frequency Is there a proper relationship between the primary output frequency and the secondary output frequency? I did check the archives, with no luck. Thank you.
