BTW, after removing the power resistor, you must be careful to clean off 
excess solder, because the crucial gap is small and "embedded" in the 
large pads.  I had to use ChipQuick to get the resistor off, then I had 
to add regular solder back to the pad to alloy with the ChipQuik, as 
ChipQuik doesn't flow onto solder wick very well.
