Kieth,
That's an interesting trick to know about, but I already invested in a 40 kV probe (and heavy rubber gloves) back when I was working around the HV section of my 475. I think I'll stick to the HV probe. I haven't worked long enough around HV to lose my skittishness about it, and "holding a neon bulb near the HV section" while it's operating is well outside my comfort zone.
