The 4.7K resistor changes the attenuation taper (and I never claimed it has any frequency contribution) - and it should be included. I get a lot or e-mails (and see postings on the forum) from folks that find that the replacement volume control changes volume too quickly on the low side. If the resistor is included - the taper follows the stock pot. So - bottom line - 1) the 4.7K resistor is in the original circuit when Loudness id OFF and 2) it should be retained if the user wants to maintain the original taper.
I suppose I took issue with your strong comment ("If you disconnect the loudness contour circuit from the volume control at the loudness tap, you remove it from the circuit entirely. Those who say otherwise don't know how to read a schematic and should not be regarded as experts") - because it is incorrect.
