RE: [TCML] NST Terry filter
Oh, I forgot that I have a couple of hundred 50 Ohm 3W resistors lying around, so a simple assembly would do I guess. But out of curiosity, if push comes to shove, would a salt water resistor do the job? Or would it's characteristics deviate markedly at high voltages? And what about a resistor made from nichrome wire submerged under water for heat dissipation?

If so, how many turns on the chokes would be required?Also I plan to replace the cap and 10M resistor string with 2 1nF 15KV ceramic caps in series on each side to give 30KV 500pF sans the 10M resistors. Is that workable?
