I do not know, if the brake down voltage decreases if the electrolyte capacitor is used well bellow the original rated voltage, but I know from experience, that if you cautiously and slowly increase the voltage across the capacitor it will work at higher than the rated voltage, but with reduced capacitance.

imply that
purposely overrating a 'lyt is pretty pointless.

Any comments on this notion?

Grrrrrrrr..  My HP16500C has a defective PS and my 4274A RLC bridge

had a major explosion inside. OMG, WHAT A MESS! All that black magic smoke!

I re-caped the bridge, it took me a day on the DIgikey site to find
replacements.

I had to use substantially larger voltages to make them fit mechanically.

But that is a good thing.

cheers, Gerhard
