After recapping the Roland JUNO-60 and JUPITER-4-- all of the Panasonic CE series capacitors have leaked out of the seals [always] at the right lead.
While I love Panasonic capacitors, this shows that after 30 years these things need to be replaced and DO NOT have magical abilities to make the synths sound better. The sound improved *after* the recapping.
From the JUPITER-4, this one unfortunately ate traces on the controller board which I repaired:
These four came from the JUNO-60:
Thankfully I had some RX30s on hand in 47uF and replaced them all:
I was not able to recap the bipolar electrolytics yet because... those aren't easy to find.
Here you'll see the blue panasonic bipolars (notice they don't have positive/negative markings unlike the nearby black sanyos):
