Clark,
R116 is normally in the bag with the BFO inductor. It sometimes gets
stuck in the bag, look carefully.
If you have to use a replacement, be certain it has a resistance of at
least 2 megohms (it is really used electrically as an insulator), and it
must be the 1/8 watt size because a larger one will not fit down inside
the toroid.
The purpose of R116 is to physically secure the inductor and provide
convenient leads that the very fine wire can be easily soldered to. It
serves no electrical purpose in the circuit at all (it is not even shown
on the schematic).
