Original poster: "Dr. Duncan Cadd by way of Terry Fritz <twftesla-at-uswest-dot-net>" <dunckx-at-freeuk-dot-com> Hi All! Bob Golding mentioned to me that someone has built a repro Poulsen Arc which was apparently of so-so utility for driving a Tesla coil. Does anyone know anything about this? I'm very into old wireless gear. Dunckx
