Bill,

I have been using vacuum 3B24s.  They are 20 kV PIV -at- 60 mA. A bit 
light for you current requirements, but you can easily double or triple 
up.  Powered by two H&R 5 kV 300 mA transformers.  You must current 
limit!

I'm now constructing a rectifier using 872 Hg rectifiers.  Ten kV PIV -at- 
1.25 A.  Will power with 5 kW pig.  I am winding the merc filament 
transformer(s) on an old 12 kV 60 mA old Franceformer NST core, also 
using its 120 v primary.
