Digi 35 CPU - new shunt resistor

I couldn't get hold of a precision shunt resistor, so I had to do with this 10% 5W one here. It didn't turn out too bad at all. This one doesn't affect the current displayed on the power supply's display (the display measures the current itself), but the current set-point in the opamp feedback loop. I have a schematic, but it is not quite matching the PCB revision I have, so I couldn't instantly figure out which pot to tweak to compensate for small deviations. Reverse engineering a schematic from a given PCB sucks.

I compared the current set on the power supply (via a keypad) and the current measured by a good multimeter and it wasn't off by more than 5% worst case. That's good enough for me right now.
