Magnetek / Parallax 6300 converter DC power noisy?

[ShrimpBurrito]

I seem to recall reading complaints here that the older style Magnetek / Parallax 6300 converter had a noisy DC output, and that was the reason for early LED failures, radio problems, and probably tire blowouts.

I have such a converter. With the TM plugged into AC power, I measured VAC across the DC output of the converter with the fridge operating on DC (a ~9-10A load), and only measured 30-50 mV. That doesn't seem noisy at all. Am I missing something?
