Repairing M-Audio AV 30 Speakers

AV30-Repair1I have been hearing a 60Hz buzz though my M-Audio Studiophile AV 30 Speakers and suspected a problem with the filtering capacitors.

One of the capacitors failed producing the nasty buzz, but it was an easy fix.

After ordering a pair of Nichicon 4700μF capacitors from a seller on eBay, it was an easy job desoldering the old capacitors and soldering the replacements.
