"and if left undamped I'd watch out for tonearm resonance"
Would a larger cap help or hurt?
"if left undamped"
There is a 100k ohm resistor from selected tap to ground. Any help?

Changing the cap value moves and damps / undamps the resonance. Here are a few values (green is always the first value swept (3.5u))
Your 100K load helps damp it a bit but you really need a lower value to show a difference.
Now even though 5K looks nice and is still 10X the source Z to keep the tech heads happy, you now have the same phase shift increase that the guy in the original video complained about. (just at the other end of the spectrum)
