Synergistic Red Fuse ...

Al, I trust the HiFi Tuning data answered your question regarding fuse resistance.  

Cheers,

GK

Mapman, thanks very much for performing those measurements. The HiFi Tuning paper Geoff linked to indicates that the difference in resistance between a 3.15 amp HFT fuse and a standard fuse was in the vicinity of 0.03 ohms, with the HFT’s resistance being lower. Given the somewhat limited resolution of your meter, your results appear to be similar.

So you’ve confirmed that unusually high resistance is not a contributor to the differences the SR fuses are making for many people. And neither is unusually low resistance. A 3 amp fuse in normal usage is likely to be conducting something on the order of 1 amp, which would result in a difference in voltage drop compared to a typical stock fuse of 0.03 ohms x 1 amp = 0.03 volts (corresponding very closely to measured voltage drop differences reported in the HFT paper for 3A fuses). And while 0.03 volts is almost certainly too small to make a difference in most or all applications, it is absolutely too small to make a difference that is consistently in the direction of being better, across a wide variety of components and a wide variety of AC line voltages.

So the mystery continues.

Best regards,

P.S: David -- very sorry to hear the news about your brother. I’m sure I speak for all of us in hoping that his condition is treated successfully.

Al, sorry to be so contrary but actually there’s really not much mystery left. Didn’t you get my memo? Yeah, yeah, I know, all the world loves a mystery. ;-) Now, don’t get me wrong, manufacturers do use a different array of tricks sometimes, like the Nano Fuse and Super Fuse from Audio Magic that are liquid filled. I can see you and Mapman wince when I say that. ;-) of course SR has "quantum tunneling" and the little black dot.

At all, even the SR claim that the WA Quantum Chip for fuses interferes with the operation of the Black fuse is probably no longer much of a mystery either since placing a WA Chip, although it’s teeny tiny, on the Black fuse could likely cover up the Black Dot, and could, one supposes, keep it from doing it’s duty. Sorry to disappoint.  On the other hand if that's what SR was referring to couldn't an enterprising audiophile place a WA Chip on the Black fuse WITHOUT cause any "interference?" Speaking of which, HiFi Tuning ships their fuses these days (or at least the last time I looked) with a WA Chip already in place. It would be really cool if the WA Chip was located on the INSIDE of the HiFi Tuning fuse but I kind of doubt that’s the case. Now THAT would be a mystery. So, I notice I didn’t get any takers on my Pop Quiz, what’s inside the WA Quantum Chip? What’s up with that?! I guess all the world doesn't actually like a mystery. 

Well everyone can rest easier now that machina dynamica geoffkait is convinced these things kick arse.   

Mopman out.
