I have encountered a problem in which a expensive solution has been
recommened.  I have a 120v/12v transformer driving about 25 12v, 20
watt halogen bulbs (I am not sure of the output current of the trans-
former).  The problem is that after the 12th light is installed,
the system begins to dim, and by the 20th bulb, almost no light is
present.

The solution (given by an electrician) is to buy an large, expensive
transformer which will supply more current.  Simple enough, I say, but
I began to think that there might be a more elegent solution (i.e. 
cheaper)

Since this is for a pre-wired house, not a lot of rearranging of bulbs,
wires, etc can be done.  Being a *lowly* undergrad in CP and having some
slight EE experiance, I began to think about putting another, smaller
transformer is parallel with the other to increse the driving current.
However, I doubt this simple idea can work and would enjoy hearing why
it would not.

I appreciate any and all discussion about my problem...

Thanks   me
