Can you make another toroid that is identical except for pickup coil with just 40 turns random wrap ed for pickup coil (all going around toroid in same direction) to compare against the MK toroid. I am very curious to see how much better the MK coil is than other coils.

I have a new Idea but your coils work great so don't worry about it.

Looking good ... i think you should try removing turns on the x2 i usually use 2x2=4 on each side.

Now if you need more voltage on the hv there is 70 turns going one way for 850 volts.

I usually get over 120 volt on 20-24 turn pickup coil , the difference may be a result of diodes , having a high voltage diode , can lower the voltage i have seen 20 to 40 volts difference between diodes.

I should try a doide because I think the bridges are to much for this coil!

Don't forget to try removing some turns on the x2 , i think you maybe losing 10 to 15 volts now, but only testing will tell ...
