ZiG's rmod is adding a resistor in series and can be done at least 2 ways.

1. Cut the bridge at R46 and add a resistor between those two points.  To undue just re-bridge R46.  Removing the resistor is optional as it would be bypassed by the bridge.

OR

2. Cut the bridge at R46 and add a resistor between the outer point of R46 and CON3 pin 3 (DGND). To undue remove the resistor.

method 2 is a bit easier because you have lots of room to work at both points
method 1 is easier to undue

I think that ZiG's discovery has additional uses. (I'll try to confirm tomorrow)
VMOD1 = 36k + ZiG's idea but using a 13k resistor (for example) would give you 49k. (not tested yet)
VMOD3 = 47K + ZiG's idea but using a 2k resistor (for example) would give you 49k. (not tested yet)
It looks useful for anyone who has done other mods but now want to try a higher resistor value.  It's possible you won't have to undue the other mod if this works.

nemercry or ZiG would know if the second part of what I posted is correct or not.  
For now, stick to the first part of my post (above the dotted line) as being ZiG's rmod.

(edit - I see ZiG posted as I was typing)
