Original poster: "RMC by way of Terry Fritz <teslalist-at-qwest-dot-net>" <RMC-at-richardcraven.plus-dot-com> For those of us with US$ 4000 to spare, this RF induction heater (1kW at 450 kHz) http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=2544557563&category=25278 would do nicely to directly drive the base of a secondary coil with topload.
