Hello Dave,

Two advantages come to mind in having a narrow gap spacing. The first is
power control. If you control the voltage to the primary with a variac, you
can operate the coil at lower voltages if the need arises. The lowest
voltage limit will be established by the minimum gap that you can maintain
which will fire. The second reason is that with a SRSG with 4 flying
electrodes, such as mine, there are a total of 4 gaps to fire simultaneously
to complete the circuit. When you multiply the single gap spacing by 4, you
will find that you actually need quite a small gap spacing to keep the 4
combined gaps at a reasonable spacing.
