Right, I hooked it up to the oscilloscope (my colleague kindly offered to let me take it home if I want to test some more).

Now, with NO LOAD, the output is very good and only seems to vary by 20mV, maybe not even that.

Sadly, I don't have anything I can load the thing with here, I'll have to hook it up to the pumps at home and see what the output is like then.

Maybe the PSU manufacturers are just covering their backs by limiting its use?

Also, back to the original question, what is the maximum operating voltage of the AQX / MCP600 pumps? Using that circuit diagram, I found the VR I need to adjust the output voltage of the PSU - it can be varied from 12.15 -> 15.25, so I could run the pumps higher than 13.8, but what is the max safe voltage? I'd be assuming in the region of 14.4, but that's just an 'educated' (hehe) guess.
