Since there is a 3.3K resistor in the filter circuit, which suggests there isn't much current draw, I ended up not adding a resistor.
I made several modifications to my SG-8 to see if I could improve the modulation, etc., including adding a tube. I won't go into all I did, it was mostly experimentation and probably not worth it.
