If you scroll up to post #53 you'll see a waveform I posted. The waveform for the 170V in the pic is what supposed to be on the scope. I thought I had it, but that waveform didn't go away when I removed the probe. So it most likely isn't from the circuit, but from the scope itself.
I recalibrated the scope per manual and I was able to get both of those waveforms in the picture from the SM. However, all other attempts to scope out other points has given me garbage on the scope. I think there might be a short in the 10x probe.
