I was trying my driverless sstc at 230v with ballast and as you can see it stopped working (the mosfet died really quietly). I need to now HOW DID THE MOSFET die ???

Because usually when the mosfet dies from overpower it just explodes violently.

And why as soon as I flipped the switch it made a huge arc and then smaller arc ?

Do you think that this can be a good tesla coil design ???

10×5 cm with around 700 turns

Best design i have managed to make

Youtube tutorial for more details (i will upload soon)

Is this a good result ? Can I make it better ?

Where can I buy a nice flyback transformer ???
