The fact is, you may have killed the NST even with the safety gap, Terry filter, and anything else hooked up! I did and none of those "safety devices" are fool proof. They do however increase our odds against failure. The "only" way your safety gap will work is if you have set your main gap correctly. This is the number 1 most important setting. This is our voltage we "clamp" at. I seriously doubt the safety gap would have saved your NST.
Most likely, your main gap was simply set too wide (in which case the safety gap would have been set wider and your NST would still have died).

I know how you feel, I've burnt two large NSTs. The good thing is that I'm fairly certain I've figured out why. It had to do with my gap spacing being too wide or my break rate being too slow [in ASRG operation]. This resultedin over-volting of the transformers and eventually death. I've built astatic sucker gap, and I test all the gap spacing before hooking up the tankcaps now." SAFETY GAP ALWAYS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
