Signal generator SG24/TRM3 - vecher - 11-14-2019

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

Yes, I can say with almost 100% certainty.

If the cap was date coded after 1976 it would not have PCB, but a type of mineral oil.

Pull it out, dispose properly and replace with a mylar type(ish) and a tie strip.

Yes Chas!

I'm seeing your response late here  for some reason.  Didn't get a notification of it.

I remember how carefully we were required to dispose of the light ballasts at work, ( and of how disregarding my supervisor was about the whole mess.)   Bad news.
