Okay, all that said -- for you paranoids out there there is another
source of PCBs that _was_ commonly used in the home: Capacitors,
especially the capacitors used in electric light ballasts. Those _did_
have PCBs in them at one time. So if you're got some 30-year-old
flourescent lights hanging around you might want to take a minute to
check the ballasts. If they don't have PCBs they will say so.

How about these huge capacitors from the demolished UPS?

The cup is pictured for size comparison.

Are they 4.1 farad each or they are 4.1 millifarad? They are rated for
300V. Are there PCB in them?

These seem to be electrolytic capacitors rather than the oil filled type --
no PCBs.
