I wouldn't think that 3000uF was necessary. Aluminium electrolytics are 
wide-tolerance devices at best, so that 49000 may be way off anyway (why 
isn't it a 47000, which is a prefered value, I wonder...)

Which reminds me of what I call the 'silly capacitors' in HP machines. 
Things like 8100uF (why not 8200uF), 21000uF (why not 22000uF), and the 
classic of a PSU with both 5600uF and 6000uF devices on the same PCB...
