Doug,
You are testing the regulation capability of your power supply.
I would say that is fairly normal - most of the drop will occur in the
initial part of the I-V output curve for the PS, then will flatten out
as the current becomes greater.
You are indicating a regulation of 3.7% over that current draw range
which is quite good.

After reading the recent comments on POWER OUT, I decided to check mine.
Using the voltmeter on the K3....
Zero power out: 13.6v
5 watts out: 13.3v
100 watts out: 13.1v
The drop from 13.6 to 13.1 for 100w doesn't seem so bad. But why the
drop when running only 5 watts out...seems out of line compared to the
100w level drop.
Does the 5 watt output V drop seem right to you? Comments?
PS is 25-30 year old Astron RS35A
Thanks,
