I decided to re-form the 450V caps via a 10M resistor
chain, so that they charged *veeeery* slowly indeed.
After 3 hours, they were still only at 120V. After 24
hours they were at 158V so I added a switch to short
out two of the 3.19M resistors in the chain. This got me
to 250V in three hours.
You'll be quite safe with a 100k resistor.

** 450 volts across 100kohms = 2 watts.
Single resistors of that value are not easy to get.
Better use a series string of say 3 x 33k, 1 or 2 watt resistors.
Agreed.
