An interesting trace. It looks like the burst of high-frequency 35V peak-to-peak output occurs for quite a small fraction of the mains cycle. And it seems to be either on or off, with no half measures. That's quite surprising, because it means the true rms voltage must be really quite low.
By the way, is that with your 100uF filter capacitor still in place, or did you remove it?
One other thing, concerning the sweep speed on your scope. It would be worth looking at the mains frequency itself, on the 5V winding of the transformer you were talking about the other day. Since that is a reasonably precise 60Hz sinewave, it would provide a useful frequency standard for checking the accuracy of the sweep speeds in the mS range.
