Back in the early days when PCB's were the cause celebre I asked the
local REMC to analyze the oil from my Cantenna. The results came back to
the effect that "We don't know what this stuff is but it's not PCB".
The Cantenna sits in my closet patiently awaiting it's next call to service.
Check with your local power company repair center to see if they have a
gallon of transformer oil available. Don't call the billing office. They
won't have any idea what you are talking about.

Having the good fortune to have used/refilled/made several Cantenna's, I
have yet to come across one filled with PCB. A friend did put me on to
Shell Turbine Oil for them as much better than mineral oil ;-)
