Sorry to hear you were tortured by the tooth doctor. That's never any fun. Well, I expected the 120 Hz energy to go up a little. The real problem in terms of overall ripple is the 2uF cap. It's just not large enough clean it up for a SET. Anyway, if ripple is acceptable without the 200/220 ohm but not OK when you install it, just add 20uF to C2 or C3 in your drawing.

TK,
Not using any 2uF caps in my filter to the finals.
C1 = 8uF
C2,C3 = 50uF
Adding a bit more filtering if needed is not a problem.

Just not sure that's enough to get it "SET quiet." You'll get it right over time though. You've got the tools and the smarts to steer it where you need it to go. :)
