@vonhelmholtz : I listen to music - not AC cords!

@thyname : I joined Agon in 2016. No need to tell you that user name. I had 4000+ posts then! Then I got a new phone and couldn't get back on here with that first user name. So I became jasonbourne52. Then that phone died when I had 2863 posts. No... 
Swiss Digital Fuse Box - "What headroom sounds like"
Claiming to hear a difference between a plain slug and a polished slug is just nuts! Back in the days of yore there was a discussion in the letters section of TAS about the sonic merits of polishing the chrome blades on AC plugs. The more things c...

Considering the miles of very fine wire in power transformers and speaker voice coils I can't get worked up about that inch of fuse wire passing 120 AC volts!

@thyname : No, I was a math major in college. Though I have always been interested in Mechanical Engineering and Material Science. Plus I am an excellent draftsman!

@thyname : That's the fault of the Agon programming! It only allows one email per name. When I tried to use my other emails I always got stuck in a loop - "user name taken" and "email incorrect"! Back and forth! So now I sign in using Facebook.

If the SDFB is not patentable then it  has been around awhile. Anybody here with an EE degree willing to discuss how it works? Or do I have to go over to the DIY forum?

@carlsbad2 : Look up "scr crowbar circuit" on Google. I'm surprised you don't know about it! It does work instantaneously! I am curious what exactly is inside that $395 box?  Micro processor Hall effect - yeah? If I had a peek I could copy it and ...

All you youngsters that think the SDFB is the bee's knees you should try the Tice Clock!

The height of audio foolery is polishing those copper, brass, silver ... slugs used to replace the AC line fuse and claiming to hear a sonic change!

This device is only for the IEC/AC line fuse. It is NOT for the B+ DC rail fuse/fuses! Apparently some here don't know this! So even if the SDFB is installed your component will still have power supply fuses in place.

Now where did I put that blue fuse? Or maybe it was the red fuse?

Even considering the part count I doubt it sounds any different than a fuse. Spending money for a nicely encased circuit board with a catchy name sure stimulates confirmation bias!

This thing is just an SCR crowbar! It is made of four parts: a silicon controlled rectifier (thyristor), a zener diode, a resistor and a capacitor. Cheap and easy to build! Put it in a fancy case and charge hundreds to unsuspecting audiofools!
