I actually have all components except the diodes. 0,1µF 1000V cap, bifilar 1,16mH coil, tubes probably.
Since i'd be very surprised if steve's little coils would survive more than a few watts i guess it's save to use 1000V/1A diodes?
did you use a sine wave or square wave?
also excel sheet for calculation with circuit 1. adjust orange boxes.
