There are two schematic diagrams showing a series and a parallel circuit that Tesla could have used. The tubes used were a common 70L7GT Half Wave Rectifer that believe it or notare still available today. I know all of you want to see this site but be patient. Here are the circuit diagrams: Just a suggestion I personally would buy only a couple of these tubes and experiment to see what kind of output that you could
expect to see. I personally have a very limited experimental budget and thus can not experiment as extensively as I would like. Here are some images of the tube.
