It's interesting that the 100Hz ripple modulation sidebands are about 20dB lower than the dominant harmonic levels.
And the IMD levels are also not (as I see it) significantly influenced by ripple sideband levels, although they show up (eg. in the 13-14kHz tones).
In either case, there is only a very low 100Hz signal showing, which is interesting, and seems to show the performance of PP output stage balancing.

If you are going toward the cleanest HT PS... give a try to the revised maida regulator.
i think you can find under "21st century maida".
I have used myself for a bipolar HT power supply (+/- 130V) and it performs absolutely amazingly.
