Why risk frying an expensive power transformer just to save a few bucks
worth of electrolytics?

If you reform the caps the way I said to, you will know before you finish
if the cap is going to be good for the long haul. I have never had one
fail that correctly went through a reformation.

That said, I have lost electrolytics when I have tried the trick of using
a variac to "reform" the whole power supply before applying full mains
voltage. I am quite sure that most of them would have reformed correctly
if I hadn't skimped on the process.

If I'm going to go to all the trouble to remove a cap I'm going to replace
it not play patty cake with it and take chances
