I have some 15000 uf, 63volt caps. If I use two of them, that's 126 volts.
Well above the 50% margin. Shouldn't this be enough?<<
IF you wire 'em in SERIES, they would also need "voltage distributing
resistors" in parallel with each. for this application, I'd guess about 1 K would
do. This would raise the "working voltage" to 126+, yes. But it cuts the
CAPACITANCE in HALF! You'd have 7500 µF total, per pair. You'd need TWO
"series pairs" (that's FOUR in all!) in parallel.
