Original poster: "Nir Wingarten by way of Terry Fritz <teslalist-at-qwest-dot-net>" <nirzvi-at-yahoo-dot-com> Hi coilers I never tried putting the spark gap in another place other then ontop of the transformer. Im now building a coil with the known 'party cup spark gap', a very simple gap: two electrods inside a plastic cup(to avoid noise) with some foil. Yours Nir(NOT NEAR) Weingarten _
