All, I have a question about some capacitors in this thing Its a Pyramid 4 UF 600 VDC Oil filled capacitor Question What type of oil is in this thing? The SG was mafe in the 50's I think..

I want to open up and re stuff them..

But with oil in them How do I proceed. Hope its not PCB oil???

Any help

Why? Most of these seem to be still good. Taking one apart promises to be a mess.

If they are leaking you have a mess already. Empty the oil, remove the capacitor, install a dry capacitor, close up the case. Don't try to refill the oil and then reseal; it's a lot of work and isn't usually successful.

It is possibly PCB ... but contrary to all the media hype, it does not kill on sight. Just be careful, wear gloves, and dispose of the oil properly. I'm not sure what properly is, but for me I'd add it to some kitty litter in a ziplock bag, wrap it in newspaper or something and trash it.

Your local trash authority probably has a hazardous waste drop-off somewhere, which may be better. ;-)
