I get 25,500 ohms reactive for the sec. That's in a good range,
I've seen good performance even when the Xsec was lower (19,800 ohm).
My old coil is 51mH, Fres = 62kHz.
Coilform is 375 turns, on a 43" x 120" form.
The toroid was 13" x 65", the new one will be 28" x 108"
You should have a lot of fun with this one.
BTW, what is the operating Vpri?
