Chris,

That would depend on the voltage that you were pushing and partially
on the physical shape of the electrodes. I think generally .2" to .25" is
considered the max safe electrode spacing for a 15 kV NST driven
system. Of course, a lower voltage would require a closer gap spacing.
With the relatively fragile NSTs and OBITs, you have to resist the temp-
tation to open up the spark gap beyond its max. safe setting to get
bigger sparks as this often destroys the transformer from overvoltage.
