Hi Leo,

Yep, likely one of the secondarys was overvolted. As othersmentioned, draw and arc to the case from each lead. The lead thatdoesn't arc will be the failed secondary. You can fix them, but it is messy.


I documented a little of my experience in case your considering it.

Take care,

Hello Everyone,
After switching from x-ray capacitors to MMC's my son's and my teslacoil was running great for about 5 minutes producing beautiful longstreamers....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 ifit would produce an arc. It did, but the wires had to be a minimumof 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
