This coil is not CW, and therefore does not have a tank plate current to dip.
What are the ampere ratings shown above? Is that the wallplug current?
So far in the low power tests (shown in the JPEG's on Chip's site), here is
what I have actually measured:
At 45 amps input (480V 3-Phase) x = 25 to 32 ft. long sec. spark

Yes, I would indeed! The full power (120kW) test will occur in about 8 weeks.
Cpri will be 0.27uF
Zpri will be 15 ohms
k will be 0.22
How does your algorithm relate output power to spark length?
