Some fuzzy schematics in this thread... don't see the resistor (lots of the relevant circuit missing), but do see a bunch of coils in series.

Edit 1: I do see a hint of the resistor (label only) on the left side (schematic is sideways) of one of the schematics. Also corrected link to post.
Edit 2: I think the resistor is in the Q hold path from some of the pics?
