Hello,
   Several months ago I posted a problem I had with a transformer
driving 25 12v, 20w lights.  The problem was that the transformer could not
drive the lights past the 12th to 14th light without dimming the whole
chain.  I asked for help...

   And I recieved it!  Many thanks to all who responded to my inqury.
The basic consensus was that IF I could match the transformers identically
and IF the wire was low enough gauge I MIGHT be able to do it.  (Some
others said to buy a larger transformer)

   Well, I conveyed the results to my "clients" (i.e. parents) and they
were overjoyed, estatic, etc.  So, they gave the printout to the 
"lighting designer" and she promptly threw it away, saying all that was
needed to be done was to move the transformer closer to the lights (
there was ~40 feet of 12 gauge wire).

   They did it, and it improved, but still not good enough...

   So, now an P.E. has been hired by them (Dad's a M.D.) and his soulution
is to buy an identical transformer, put it in the old place (~40 feet away
from the lights) and put the old transformer next to the lights.

   QUESTION:  assuming a lenght of 35 feet of 12-gauge wire between two
              750 watt transformers, will the house burn down or the
              transformers blow up first <grin>.  Or, by heaven's grace
              WILL THIS WORK???

   Thanks in advance ....
