Like early and late NBT’s, ya gotta know the vintage.

I gave up on SST’s 10-12 years ago, found them to be too irratic.

I hear the later ones are better, just haven’t gotten around to trying them.

Am using and liking late mfg NBT’s. Had given up on them, too. But that was back in the day when they seemed to blow up way too often. I get good performance with the current ones.
