RE: Primary: flat or conical ?



It depends.  If your secondary diameter is small (<4.25"), a conical primary
offers better coupling.  Larger diameters have better coupling by themselves
so a conical primary isn't necessary.  Also depends on how much power you're
pushing.  The conical will reduce the strike distance between the top load
and the primary.  If you're pushing a lot of power, you'll have primary
strike problems with a conical.  You may also need to use a lower coupling
with a high power coil to achieve better quench.
