I fully agree that without a primary inductor, the cap may be
overstressed due to high discharge currents. But the spark gap will
limit the maximum cap/NST voltage in the same way that it does in a
normal configuration, so over-volting things is not an issue. I once
did some coil testing where I didn't want to have my primary or
secondary hooked up, and instead wired in a series-pair of 500W halogen
lamps in place of the primary as a dummy load. Of course, it you omit
the spark gap, then you're REALLY asking for trouble...
