True, but we only use 1A. I should confirm this, but I took the 47K Ohm
resistor to mean "able to source at least 1A", meaning that it would be
possible to ship a different supply and not violate this. I know of no
plans to replace the supply with one that can only source 1A, but that
is a possibility.
I'll look into this.
