If you have many of these electrolytics available, what you can do is
simply measure their capacitance. For your DC smoothing/supply cap you can
take those that have about the same capacitance.
Even then, adding a parallel resistor to bleed off the charge from each
cap would still be a good idea, that way you'd know that in at least X
seconds the cap bank will have discharged to a safe voltage level.
