Tim Mrock was ahead of his time. His stuff was and is awesome. But nobody keeps great stuff like that secret for long. Lots of people are on to it now. NPS1260, what do you think that is? SR fuses and outlets, the glob of gray goop they tell you not to remove, what do you think that is? I'll give you a hint, the top end QSA Red and Black fuse uses so much they had to stick a piece on the side.
Millercarbon are you saying the key to these fuses is amount of 'special secret sauce' contact enhancer applied?
I always thought SR and new guys like this Quantum were using some kind of voltage conditioning process on the fuses, and the fuse price/level was just the amount of time that fuse spent on the conditioning device.
But if the key is contact enhancer, then it becomes easier for DIY to replicate.
