Simple to build isolation transformer that consumes less power than it gives out

Still looking through my junk piles for some 1:1 isolation transformers.  It just occurred to me that some of the old computer UPS units probably have 1:1 transformers in them as they pass through 120 AC when not running off the battery.   Getting ready to pull a couple apart to check it out.  As I've gotten some cheap at garage sales this might be a good source for higher power 1:1 transformers since they seem to be quite expensive from sources I've seen so far.  I'm not sure on this but will post later what I find. 
   
   Old Tripp Lite had 3 transformers but no luck with 1:1's.  Still a few more to check out.   Now I'm thinking old high end audio equipment may have some.  got some of those laying around too.

E2,

All switch mode power supplies such as used in computers has a 1:1 Ferrite transformer at the AC input line.
The transformers are small but could be used at lower wattage for testing purpose.

Well, earlier today I ordered two isolation trafos that I found on-line --  on the right in attached.   $11.66 each, from Allied Electronics.
The one on the left, toroidal, is also an isolation trafo and almost did that, but cost $18.11 each... maybe next time, but soon I'll have the two little guys (1.7lbs each actually).

  I was surprised I could get these at such a low price.   

Thanks again, Jack!   lots of fun and adventure thrown in...

Single or double transformer arrangement requires higher impedance primary than secondary? Is this correct?
