Aaron, you needed such a low scaling resistor because you must have higher initial bias voltage to start with and/or your tubes needed a different bias voltage than Mr. Fender expected with those tubes in the good old days.
Higher line voltages could make the voltage on the bias tap a little high. Your adjustable bias circuit obviously now has a range more suitable to the tubes your using. You mentioned a 70 volt upper limit when you started your posts. That's way too high to be useful - the tubes would likely be completely cut off long before that.
It works! Be Happy!
