Hi,

does anyone know if PCBs were ever used in the tar potting of old neon 
transformers???  When i picked up some NSTs today, the man at the sign shop 
mentioned i probably should not try to depot them as there may be PCB in 
the tar.  But now that i think about that, i would think they would have to 
use better methods of sealing off the case of the NST, if that were true 
(but then again, they didnt really think PCBs were bad at the time of its 
use).
So to make sure, did the use PCB??  It makes me worry when i think of all 
the old transformers i unpotted!

Steve Ward,

PS, i hope im not setting off a false alarm. if so, sorry about that!

PPS, is anyone else having a heck of a time getting NSTs???  The sign shops 
dont want to give up the old ones, and say that the price of new ones is 
sky rocketing.
