I've gotten the wild hair to replace some of the older caps in my current lineup of speakers, UREI 809 (original series) and JBL 4425s. They're all original but I note that there are some electrolytic caps on the UREIs that most likely could stand to be replaced since they were in pretty constant use through the 80s and 90s from what I know about their history at Fantasy Records.
So, the query is: What experiences others have had in replacing (not modifying) the original components in their older speakers? Good/bad/indifferent?
Many thanks for your considerations and comments.
Cheers,
David
