MMC capacitors exploding on my tesla coil, I need help!! Im in a tight spot. I just recently built a decent sized tesla coil. Everything works flawlessly except that my capacitors are melting. They don't fail but they emit flames or they arc, (its hard to tell). Then after inspecting the capacitor bank, you can see that the capacitor has melted through. It still works but soon the capacitor catches completely on fire with flames licking the other capacitors. The curious part of this entire phenomenon is that its the same capacitor in the same spot. No matter how many times I replace it, it first glows, melts, and then burns. However, for whatever reason, instead of melting, the resistor just disintegrated instead. I have also noticed that when running my coil at night, 2 or 3 other capacitors have this bright ominous blue glow on the ends. The capacitors are rated for 6.5 kv DC which is more than enough. I have 7 rows in parallel with 5 capacitors in series. My NST's are each rated for 15 kv @ 60 mah but wired in parallel for 120 mah. I have replaced about 8 capacitors so far. 5 came from the same spot while others just ocurred from the spark gap being too large.
