RE: [TCML] NST Terry filter
Would these resistors do? http://docs-asia.electrocomponents.com/webdocs/0031/0900766b8003123a.pdf I found them on RS online as the L100J1K0E is out of stock in Singapore. I am afraid of arcing to case occurring for these aluminium housed units though.

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?
