I have a powersupply which have been stored for 15 years.
Now I want to use it. But I think the high volt(500 V) capacitors
need to be refreshed (right word?). (To slowly increase the voltage.)

This isn't quite what you asked, but I'd recommend just replacing them.
Electrolytics are notorious for drying out and 15 years is really
pushing it. I'd just replace them with some new ones.

I agree with Bill, for the cost involved and the impending failure just
replace them. The power supply will be good for another 15 years and be
trustworthy. If one of the old caps fails it could take out the rectifiers
and chokes, not to mention the mess.......Eddie
