You don' t have pcbs.  Pyranol and dykanol are volatile, thin fluids with a distinctive sweet odor.  You have plain old mineral oil. Sticky and stinky, but safe.  White gas is a good cleaning solvent for the mess. Scott

Never mind teaching your three sons how to make metallic mercury from 
mercury battery guts and then finding little mercury balls in the rough 
areas of the concrete floor many years later...

    Never mind playing with liquid mercury and watching it skitter
      around in a container.

        Neither Scott
            of I suggested draining the rest of the oil. Just seal it up
            properly. I am 71 now and when I was a kid I used to take
            caps apart for fun. Used to swim in PCBs. Who needed gloves.
            Had asbestos lined bench also. Same where I worked as a tech
            in the late 50’s and 60’s. Still here, HI. 73 – Mike

        Think if I
            tried to drain remaining oil it will never all drain and
            always have something that’s a lot like a cross between
            motor oil and tar that will be leaking out so if anything am
            inclined to do complete replacement of innards with the
            option of cleaning out shell. The amount that has leaked is
            only a small fraction of a once but a little bit of that
            crap goes a long way. The thing about cleaning and sealing
            is the capacitor is eighty years old and in addition to the
            small amount of leakage is it possible that some moisture
            has entered over the last eighty years and contaminated the
            capacitor? I may try connecting one up to two or three
            hundred volts and seeing if it develops more leakage or
            internal heat. Don’t think this radio has had any voltage
            applied to it in decades. The capacitors like everything
            else in the receiver or RCA manufacture so what the status
            of PCB use was in 1936 is a good question. Years ago had to
            do PCB removal on broadcast transmitter and that was a big
            deal where you received a five gallon can along with apron
            and gloves and deposited the offending capacitors into the
            can then also the protective clothing and everything else
            into the can and sealed it and sent it off for proper
            disposal, and that was for capacitors that were not leaking.
            Between radium paint and PCB oil wonder how many of us are
            running potential toxic superfund sites?

        That was going
            to be my answer as soon as your post came up, but, I figured
            you were going to be saturated with replies, so decided not
            to bother. 73 – Mike
