There are very good and cheap surplus alternatives to Digikey.  All
Electronics has ceramic disk caps, 1000pF/10kV for $1 each.  Two in series
on each side of the NST will do the trick (cweramic caps are fine in this
application).  Other surplus places will have acceptable wire wound power
resistors, but you'll have to check their catalogs or web sites.  I've
listed what I feel are the best surplus vendors with contact information on
my web site at http://www.laushaus-dot-com/tesla/partsources.htm.

trying to build a nst rc filter (as per terry's paper).
trying to make sure i match the right components.

checked out digikey...
found some ceramic disc capacitors rated at 3kv(dc)
  such as p10842-nd (p606) at 3kvdc / 150pf. approx price $0.20
i'll need quite few to make the 30kv rating.

found some power resistors
vitreous enamel wirewound power resistors pn avt200-1000-nd (p639)
rated voltage is 1kvac  approx price each $17
225watt.

are these acceptable choices?  I'm quite awful at component selection :)
im guessing that doorknob caps would be expensive if purchased new.
I've seen them occasionally on ebay, but i figured i should build
with new components.  i don't expect to build another, so i might as well 
build it right.  I'd like to make the rc filter able to withstand
12kv/120ma.

larry.
