I may be mistaken, but I think that polychorinated biphenyls were used mostly in metal contained components such as "bathtub" and other metal-encased capacitors, and also some encased transformers.
But truth told--even if the juice of any ruptured or vented capacitor in a set is not PCB-based--you might still consider it unfit to use as an ingredient in your salad dressing, and none of these capacitors really are good for the safety and quality of the aquifer if tossed in the landfill....
Just my twopence....
But I admire your conscientiousness, jeyurkon.
