Must be... the designer chose a 7 watt rating for the 500 ohm resistor... that would imply that something like 0.1 amp or more (DC or average pulse) is flowing through the resistor or else the designer would have chosen a lower rated (cheaper) part. The "ground" lead of the tripler must be at least 50 volts (DC or average of higher pulses) above ground for the 7 watt rating of the resistor to make sense. Without knowing the digram of the tripler or what it is connected to, the source of the voltage is not known... but for sure the "ground" terminal of the tripler is *not* at ground potential.
