Thanks! I figured as much. I was looking at the available devices and I think I'm going to buy the 500V pot. It's about $20, and I can reuse it in the future. I will tweak the pot until I find the right spot and then put a fixed voltage divider at the correct values and leave it.
That way I can take it out and use it again. Also, there isn't really a good spot to put such a device when it's closed, so it's better if I just put some 1 watt resistors in it's place.
I thinking about now how I would wire that in. Should I put in between the 500V source and ground? Seems like I should just use the F1 spot for the far side of the pot because it's zero volts.
