High Voltages With Caps & Diodes

For the circuit below, the components will need to be rated for high voltage. Suggested cheap rectifier diodes are type 1N4005. Be careful not to kill yourself. The capacitors can be 1000 pF (1 nF) 1000 volt disc ceramic types. Higher capacitance values will produce more current available at the output.

This circuit is the classic voltage multiplier, used in some oscilloscopes for the CRT final anode
