Replacing E-MU 1820m caps

After more than 10 years my emu 1820m started to play noise when i tried to play music. Sounded like “white noise” and 15 minutes after every boot the noise seem to be disappeared.

When I dissasembled the dock unit I realized 2 buggy capacitors, and replaced it with 680uF 25V caps (bought from local electronics store).  After replacement the noise disappeared immediately:
