RE: A question about alternative power supply for hp41 series
LOL, generally in the sparky world you don't worry about a power supply misbehaving at low loads, but I could see down in the micro-amp region, things might get a little unspecific.

I recall back in the 80s an engineer friend of mine noting nearly unloaded, or lightly loaded generators on aircraft engines can be a problem since what little load there is might 'hunt' between paralleled generators on the plane, and in the case of a 4 engine plane, as the load 'moves around' the plane can experience slight changes in engine speed if the load shifts from, let's say #1 to #3, and that can make for slight, and annoying, changes in the direction the plane is flying. The autopilot (or the real deal behind the yoke) can compensate, but having a plane with perceived directional instability is comparable to a car with loose steering.
