[Heathkit] Need Help with SB200

[wb8jkr at juno.com]

  There is no RF at that point, a wire wound would
work fine, but the value needs to be correct
in order for the meter to read correctly. I would
also install a pair of cross parallel connected diodes
across the meter movement to protect it.

 Might not be a bad idea to make sure neither of the 33
ohm grid resistors have opened.
