[TCML] Torroid/Shorted Turn?

[Peter Terren]

I remember asking this question 5 years ago. The coupling is low and it has 
been shown by computer modelling and in practice to make no difference. Even 
from the early days of toroids I seem to recall ? Bill Wysock or someone 
sawing a notch in their toroid for no benefit.
Just don't expect it to make no difference near the primary end...
