Eight spark gaps may be wasting excessive energy in the form of heat and
light --- especially heat.  You might try just one or two gaps for best
efficiency.  On most of our 30 mA and 60 mA coils we use just three 1/2 dia.
tungsten electrodes to form 2 sparkgaps.  Only on the 60 mA units do we add
a 100 CFM fan behind the gaps.  30 mA doesn't require any cooling at all for
best quenching.

Also, experiment with elevating your sec. coil in 1/2 inch increments until
you hit the best coeff. of coupling.
