Problems do exist. Diode multipliers generally tend to blow up unless
you have payed enough consideration for transients. Most often problem
is to forget that a short circuit at output  etc. may lead to large
in diodes. Stored capasitor energy is also dissipated somewhere when
the output short-circuits.

Solving all problems can lead to *very* bulky and expencive filters for
dc bus (to limit peak currents). Not fun.

You better off with neons.

Nice to see yet another Finn on the list :)
