Thanks for that Chuck.
However it still leaves the problem of potential PCB contamination: did they, or did they not use PCB's? If it is just mineral oil then there is no problem, I'll either refill, or more likely remove and replace with modern capacitors inside the can. It's the potential for PCB poisoning that concerns me most at the moment. Bri "Chuck Harris" wrote in message ... Bri wrote: Because the oil has leaked everywhere... "Brian Goldsmith" wrote in message ... "Dday" wrote 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. Brian Goldsmith. 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. -Chuck |

When PCBs were popular, they were considered such a wonderful thing that manufacturers would brag about them on the case as using SAFETY OIL. --scott -- "C'est un Nagra.
