JavaTC calculates the ideal value of capacitance to ensure maximum charge and peak energy transfer, and thus best efficiency. However, it is not always practical to build a "perfect system" in which the capacitor matches the HV supply and the resonant frequency of the secondary coil. The most important spec is the one that gives your primary tank circuit the correct resonant frequency to match the secondary (under load, including the capacitance of the streamers themselves). You do that, and you'll have a good TC. The holy grail of TC building would be to match the Fres of primary & secondary circuits AND match the tank cap to the HV supply, though you can still have an excellent result without the latter.

Subject: [TCML] Is this still correct, javatc
With javatc I noticed that it recommend a 55nf primary cap for use in a
srsg, 4 neon 15000/30 system. But after loads of reading I have not seen any
one actually use this value or even close to this. Seems most say .031 or
something close. Is javatc recommendation of 55nf alright to use or just a
ball park. Thanks
