Mystery inductor- 37-660
#1

I'm not holding my breath waiting for an answer but here goes:

On the 37-660 IF amplifier (6K7), the suppressor grid (pin 5) has a coil to ground. Since my radio has been tampered with, this coil is missing. There is no component designation for this coil and the schematic is kind of blurry.

What is the purpose of this coil? I'm inclined to replace it with a couple of turns through a small ferrite ring or simply ground it and hope for no spurs or stray coupling. Can anyone tell me what the schematic is supposed to read?
