I found some photos of previous multiplier prototypes I built last year. The Image on the left is the very first set which were a 20-stage negative multiplier and a 20-stage positive multiplier. They produced several microamps at +/- 26kV and used a electronic ballast as the input source. The image on the right is the first resonant multiplier board. The board includes a resistor voltage divider and was designed to be oil immersed and produced a few hundred microamps at +/- 40kV using the same ballast as input.
