With these latest specs, I got about 15.1 turns on the primary. However, as
John C. has
mentioned, the c-c spacing needs to be corrected. Haven't done this yet.
However, you will
get slightly different answers for the tune point. I personally would make
the primary about
2 turns over your largest value just incase.

I'm hoping to get to the c-c spacing issue tonight.

Take care,
