Original poster: "Mike" <mike.marcum@xxxxxxxxxxxx>Sounds like 1 side of it is. Try drawing an arc from each end to the case and see. As a quick fix you could try baking it in a 200 degree oven (or something similar) for a few hours if a carbon track in the tar is the problem. If it's an internal winding short you will have to replace it (unless you have alot of time to depot it and fix it). Before dropping in another I'd fix the problem that killed it in the first place (gap too wide with a resonant cap? no terry filter? primary strike?).

Original poster: "Hajdrowski, Leo T." <leo.hajdrowski@xxxxxxx> Hello Everyone,After switching from x-ray capacitors to MMC's my son's and my tesla coil was running great for about 5 minutes producing beautiful long streamers....what a sight!Then it just stopped. I disconnected the NST xfmr (12KV - 60MA) from the coil, connected a pair of wires to the terminals to see if it would produce an arc. It did, but the wires had to be a minimum of 1/4" away before the arc would start and it would grow to only about 1".Is my NST fried? Can it be fixed? Thanks. Leo
