Is it a general rule that the more power you put in, the fewer turns on the 
primary you have to use? I ask because i am running on a 12/60 nst now and 
i had to add 5 extra turns (and they hang off the side) to my primary, and 
i want to make sure i won't have to add any more (i am getting another 
12/60 nst soon, for 12/120).

Thanks
