470uF is a large value electrolytic capacitor. I wonder whether such large values can be reliably "measured" on capacitance meters. It is not something I ever tried. Much more valuable with electrolytics is to test their ESR, effective series resistance. That part probably has high ESR, and would be easily identified as bad on such a meter.
Excellent news that you got the set working again!
