I have the same resistors in my Terry filter, the pdf link you provided shows 2845V for the L100 series

On the Terry filter, I see these suggested:
http://www.alliedelec.com/ohmite-l100j1k0e/70022726/#tab=specs
But the specs say they are only good for 10VAC. I imagine the voltage seen
across these resistors will be much much higher than that - or am I missing
something?
I found a few 200Watt 1KOHM ohmite resistors at ax-man for a few bucks a
piece but they are shorter than the above linked model, and apparently
rated at 1800V.
I'll be working on the coil form first, and during that time also the terry
filter. I don't intend to turn anything on until the filters are in place.
I found a 20A EMI filter at ax-man for $3 I think that's a decent price.
Thanks,
Matt
