Terry,
For a wirewound resistors the parasitic inductance is considered to be...well...parasitic, right?
So much so todays WWR are done in bifilar way so to eliminate it.
So other than stability of a wirewound, I don't know what other reasons they would have.
But as the stability goes, the rest of the resistors were carbon, so to have some resistors stable and some not.....
The cathode resistor is DC bias / Negafive feedback, so stability might be a consuderation but then there are other circuits with higher value dividers that could benefit from stability, but used carbon resistors nevertheless.
Maybe it is simply because it was easier to make the low value ones from a wire and higher from carbon? Just technological, no circuit theory behind it?
