As a (retired) career power company employee I can say with
reasonable certainty that the "transformer oil" that was available
to --most-- scrounging hams since the introduction of the Cantenna
was -unlikely- to contain PCB's.
At least in the circumstances familiar to me, PCB-containing
transformer oil was mostly long gone by the time the Cantenna
was introduced. It was certainly gone "as new" out of the barrel,
but did remain in transformers already in place, but few if any
hams received their oil from a transformer. (:-)
It doesn't "make it right", but we had transformer shop employees
that literally stood chest deep in the stuff inside large substation
transformers when they were overhauled or a tap needed changed.
