Not only that, but i find that my coil prefers slightly different phasings 
depending on the night (perhaps the weather?).  Its usually a tiny change 
in phasing, but its definately noticable.  So using an electronic phase 
controller is really the best idea.  Get it phase mechanically with the 
controllers variac set for maybe 1/2 way.  This will allow for anything then.
