    Discolouration on top?

    This is on a Nichicon VR Series, 11th week of 2003.
    Does discolouration like this indicate a bad batch?

    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.
