I'll have to set up the test again and measure voltage drop across the
leads and the voltage directly at the power supply supply terminals.

What I bought is a 15V open frame supply from allelectronics.com for
$11.50. It turned out to be a very high quality power supply (Digikey
has the same unit for almost $40) This PS does not drop volts even
with the line input and load well out of spec (I tested 63VAC input
to a 4A load briefly) ...
This is the one I bought

I ordered two of the above mentioned power supplies. They arrived
today. I tested both of them.
Neither holds 15 volts. At 2 amps they are down to 14 volts. Even at 1
amp they are down to 14.5 vdc.
The total regulation specification is +/- 5% so within 14.25 to 15.75
volts under all conditions. How high was your lead resistance?
