Hi Greg,

I found a Fluke HV probe used for $25 from a company in Arizona.  Works fine. 
 Unfortunately I have forgotten their name, but I found it rather easily by 
using a search engine on the product number -- 80K-40 for the 40kV model.  
That's probably cheaper than you can build one that is accurate and safe to 
use.

Alternatively you can feed a small voltage into your MOT primaries to see 
what the stepup ratios are.

Regards,

Michael Tandy
