I would love if some one could explain and post pictures of the 120 Ohm resistors in series with the headphone jack on the SEX 2.1. I need to add them to cut down the hum for my D5000 headphones (25 Ohm, 106 dB/mW) and I cannot seem to find any dedicated threads. Since this seems to be a common question, this could be the new go-to thread for it. Thanks in advance.

Have a look at the schematic attached, that's where you want to add them for the left and right Channel, i.e. between the two red wires and headphone socket.
I've attached a pic of mine, though a little more complicated as the wiring runs to the XLR socket on the left, then onto the regular TRS socket on the right but the principal is the same, snip the red ones and insert the resistors into the path.

2W would go through if the transformer had a 120 Ohm tap.
1/4 Watt is sufficient for this purpose.
