Well, more or less, yes. I was talking more about collector voltage. If your desire is to mimic the sound of an original unit (it may or may not be), then you should take impedances into consideration. Large changes in resistor values will change impedances (and any HPFs and LPFs) within the circuit, and thus change the sound somewhat, for better or worse. This is a reason to select a transistor that gets close to the "best sounding" bias point with the original circuit resistor values. (Caps influence sound too, but not DC bias). That's where a ballpark "target" collector voltage becomes useful here, in selecting the transistor. But you should still allow yourself to make smaller adjustments to get the "best" sound from the particular transistor you used.
The original Rangemasters didn't have bias adjustment trimmers. Even though they had a much larger supply of Ge transistors to select from, I'm sure there was still quite a bit of sonic variation from one unit to the next. Even at the same ambient temperature and battery voltage.
Another detail to consider in this case, two resistor values were different between the OC44 version and the OC71 version, from online pictures I've eseen. So there is no "one" Rangemaster sound anyway, maybe more reason to feel free to tweak the values a little to get the best performance for your needs.
