Re: equalizing resistors across series capacitors. I'll use rough values. You have two 500 uF capacitors in series, with about 500V across them, total. That's at least 250V across one of them. A 100-ohm resistor here would burn an incredible 625 watts. I would try paralleling about 500k across each capacitor, and then testing the voltage in service to see if the capacitors have approximately equal voltages across them. If not, then lower the resistor values, keeping in mind that V**2/R is the power running through the resitors. You may need to use high wattage resistors.
