BTW, Biii - tip/suggestion - for those series-connected electrolytics you
probably should put a pair of equal value resistors - one across each
series
capacitor, as the leakage currents will not be equal in each capacitor in
each series string and the DC voltage won't divide equally across each
capacitor unless you put individual "bleeder" or "swamping" resistors
across
each cap in the series pair to equalize the DC across each capacitor in
the
series!
It is worse than that.
With a single bleeder for two series capacitors, the capacitor with the
least capacitance will always be reversed charged upon every power down. So
even you have equal voltages by equal leakages, you have to add a parallel
diode or the discharge will reverse charge the cap with the lowest
capacitance value.
