How to handle very old caps

[Bassterror]

Hi

i just got some big "Sprague" Caps via ebay.
They were very Cheap, unused and about 20 years old...
Must have been in Stock somewhere...

Any Idea what is the best way to "wake up" these fellows?

Do i have to fear serious drawbacks when using them for my TDA7293 PSU?

Greetings,
Stephan

You can reform electrolytic capacitors even after many years... Do a search here on the forum or with google on reforming.

Cheers,
