Ive come to the conclusion i may not be able to fix this probe. But I have still learned alot so it was worth the 60 USD and teh time lost trying to fix it.
First, the capacitence (3pf) at 60 hz was enough to damp the 10kV sine signal to just 28 mV! through a 99.8 Mohm resistor. And though the compensation box is hard to fix, when my body's stray capacitence was attached to the LV node, the O-scope showed a perfect 17V sine wave. so capacittance does play an enormous role in how these devices work.
I continue the my building of my own probes.
