[Milsurplus] NAVY LM-13 FREQ METER

[Richard Brunner]

Mop some up on a cotton swab and see if it burns.  If it burns it is not the 
"awful PCB."  PCB, more accurately  known as Askeral was made to not support 
combustion, and that's it's only virtue.  It has a higher dielectric 
constant that oil, so it "could" have been used for capacitors, but I've 
never found one.  It was meant to be used in transformers used in buildings, 
mines, and chemical plants where an oil fire wouild be catastrophic.  It was 
also significantly more expensive than oil, and was not used without a good 
reason.  If you don't ingest it or put it in a open wound it won't bother 
you.
