Oops, i missed this before my previous post.  Thanks for the schematic Sue. 
Im a bit confused about the power input to the rest of the circuit.  If im 
simply using a MOT with only 1 HV out, do i simply connect the 2000v out to 
the RFC and the ground of the transformer to basically everything else that 
is grounded?  Do i skip the .8uf 2000v filter cap?  Do i need the .001 5kv 
cap as well going to ground? I also have a few questions about some values.

What is the construction of the 65mhy RFC.  I have some 28, 26, and 24awg 
magnet wire around if i could possibly make this inductor.  I dont know how 
to calculate that though.  What did you use?

What is the purpose for the .001 5kV cap going from 1200v to ground?

What is the voltage rating of the .0035uf cap going from the plate to the 
primary?  IS this the cap that causes sputter mode?  Does this coil even use 
sputter mode?!?!

Whats the Voltage on the filament bypass caps?  What is the purpose of 
these?

How critical is the value of the resistors on the grid circuit?  Would 5K 
ohm at 20W work?

What is the diameter of the primary coil?  And what are you using as a 
secondary and top load?  What are all of the wire guages?

This circuit looks appealing, how big of a spark does the raw AC feed give?  
Sorry if im bugging you with all of this, but hey thats what the list is 
about;)  Thanks,

Steve Ward.
