This is an early shot of work on the present device, The lower device is the heart of a test unit created in the early 1990s that was totally made up from welded poly propylene. The bulging lower rings were condensers wired as a neckless much as the twitch coil leyden jars are laid out in the present device. When the early device was tested a wire came loose and the energy surge blew out several of the built in condensers. rather exciting! I was unable to repair the damage. pg
