Why would you want to replace the oil capacitors anyways?

They are still good. They have lasted 60 years and they will undoubtedly
outlast us both.



****Reread the OP original posting," I have 2 such sets, one of which is
weeping like a baby". They are obviously NOT good.

clean them up, with naptha, replace the lost oil (mineral oil is fine),
and replace the damaged rubber seals with a good quality silicone sealant,
and the capacitor will go another generation...assuming that it didn't
already arc over.

Oil capacitors have paper as part of the dielectric, but the paper isn't
where the characteristics of the capacitor come from, it is the oil.
The paper is just a convenient separator for the plates.
