[Milsurplus] PCB'S??

[bavarianradio at comcast.net]

Hello all, I'm beginning a restoration of an RBA-3 WWII receiver. It appears that ALL of the rubber grommets on the oil filled bathtub capacitors have failed. They appear red in color and are sticky and gooey.  I have been careful not to touch these (too much anyway) and I wash thouroughly after working on this radio.  The question is....  are these caps filled with PCB's?  and if so what precautions should I be taking?  On a different note, remarkably the radio was working before I took it apart. I was going to clean all the switches and pots and touch up the alignment, with recapping occurring after a performance evaluation. When I saw the condition of the seals, I thought I had better recap first.  I have a RBM-5 set here also that plays with the original caps and performs nicely! ( I don't leave the room with it on, however)  The caps in the RBM look like new compared to these.  Any thoughts?? 73's Ross
