Yes. There was a design for an EHT probe like this in 'Television'
magazine a few years back. These EHT probes as just a
high-value resistor (a few hundred megohms) and a
microammeter in series.
The main problem is keping the resistors well enough
insulated. Remmeber it has to stand 30kV or so.
Hmm. I think I'd be better off buying one for now!
