surplus bargains, PCB's



Hi All,
 Thanks for answers to my previous post.
 You guys are the only ones who can understand my 
pleasure with my surplus bargains. A complete X-ray power 
supply for $50.00. And a 5Kv DC supply for $20.00. I got 
a 120 volt - 20 amp variac, 240v-20 amp variac, 60kv 
meter, 500 milliamp meter and all sorts of other goodies. 
Metal cabinets, caps, etc. All from the Arizona State 
University surplus warehouse.
BIG CONCERN! PCB's in the X-Ray transformer. I did check 
the archives on PCB's and X-ray. The stuff does float on 
water. But, it is yellowish in color. Does seem to smell 
like motor oil, not chlorine. What does benzine smell 
like?
 The archives did not seem concerned about PCB's in X-Ray 
xformers. There is at least 10 gallons of oil in this 
thing. I asked about PCB's, they had no clue. I would be 
dissapointed if a "learned institution" would sell 
outlawed chemicals to the general public with no 
disclaimers.
 The transformer is a Phillips Type 42117/B.
 Any advice would be well taken.
A slightly concerned coiler.
Thanks all,
Allen Cart
