[Elecraft] OT: Transformer oil in DL's

[Merv Schweigert]

I recently bought and dismantled a 50KW AM station and the transmitter 
was a
Harris,  made in 1979,  the transformer tested for PCB.  The capacitors 
were ok.
I checked the manufacturer of the transformer and they provided info that
they used PCB oil until approx 1979 or 1980. 
So unless you know what is in it,  dont take the chance.  
Had the transformer removed and the area cleaned.  Not cheap as there is no
toxic disposal on Molokai,  all had to be shipped off.
