[Amps] "Stacking" power supplies?? how?

You might want to look up the connecting wire resistance per foot. Some  
length will provide the small voltage drop mentioned by Bill.

REPLY:

The usual way is  to insert a small value resistor in the + lead if each 
and then
parallel  them. The value of the resistor should create a drop of about .5 
V or
so  under full load. Be sure the output V of each supply is adjusted to 
match  the
others as close as possible.
