Original poster: "Tristan Steele" <tsteele-at-westnet-dot-com.au> Hello All I am relatively new to the world of High Voltage, and am considering building my first tesla coil. The thought that I am having is that wouldn't it make more sense to use a rectified output (ie. DC) to charge the primary capacitor. Is it possible to run a tesla coil on DC power? Tristan
