I have a fairly full list of PCB containing components issued by the 
NZ Ministry of Health. It is more aimed at common fittings but does 
list trade names for some of the nasties contained in many caps and 
transformers. A couple of examples of safe ones:


Both of these were found in transmitter smoothing caps which have 
similar ratings to those you describe.

Some nasties by name:

DUCONOL (Dubilier), PYRANOL (General Electric), THERMINOL (Hunts)

The list is not exhaustive. Look for any of the above words on your 
caps. In particular, look for anything ending in "OL". I need full 
details in order to have a reasonable chance of identifying these.
