> The older transformer oil contained PCBs.
PCBs were banned in the late 70's and were to 
be removed from service. It is unlikely you will
find any PCB type oil now.

> exposure to PCBs can possibly lead to cancer
This is based on a study from Japan where PCB
oil was mistaken for cooking oil and was
ingested. Other studies are inconclusive.
But, why take the chance.

Transformer oil is based on mineral oil with "things"
added in to improve the heat transfer, and lower the
flash point.

Just FYI.

Where do you get ICE bandpass filters & beverage matching boxes?  The
same place that pays for the hosting of this list:  The eHam Store.
