I got arcing all over the back of my board so I turned off the power, pulled the board and looked at the back. There was no sign of any electricity at all, it looked as new as the day I bought it. So the 15kv is skating over the surface without burning the copper. Attempts to remove the donuts have been fruitless. So I'm rebuilding my filter on a piece of solid lexan with custom drilled holes for the parts and an additional lexan strip glued down the center of the board to act as a damn. I slapped my forehead when I realized how naive I had been!
Oh and I tried the "strip the shield off the video cable" trick to make HV wire and the stuff is useless. It burns through when close to anything else. One thing I did that turned out to be a total success was using twist lock bnc connectors for my hv cabling. Those things perform like a champ!

Noob coiler here, putting together components for a 15kv NST SGTC and was wondering if a $4 Radio Shack resin perfboard would be okay for my terry filter? I've noticed a few people using higher quality (or at least I assume higher quality) fiberglass perfboards and I wondered if it was maybe because of potential heat issues with the bleed resistors or something like that.
