Yup, talk about your patents day in day out but expect us to find them from months and months sgo ... With the search here. Okay ....
The guru on fuses:
For two years, I have asked why and how fuses could possibly matter. All I got was arguments of faith, pro or con. I needed a real audio guru who actually knows. Here is a link from John Curl’s discussion on Parasound’s website. He engineered and designed some some great equipment, including some Mark Levinson gear, The Grateful Dead’s 30 plus McIntosh amp powered Wall of Sound, and his admittedly, somewhat price compromised Parasound designs. He discusses the electrical properties of standard fuses, showing how they are compromised. The entire article is quite enlightening, but to skip to the fuse section, go to the bottom half of page 6. https://www.parasound.com/pdfs/JCinterview.pdf

Months ago I posted a link to one of my patents..I never said on this thread. Pissed that people think I am a liar. Been on here for years..no need to prove myself to the ignorant dilberts. They should make their own discoveries and findings let them post their own patent links. They have disabled hearing. And now for some chilling. Tom |
Someone directed me here. So I just wasted the last five minutes on this drivel. The one entertaining bit, the "don't care" kids who all hear the difference so easily they can only think anyone who can't is like grandma, they can only hear you when you shout in their ear. Only in this case they not only can't but won't hear. And their heads are so thick nothing ever gets in that way either. This all makes perfect sense in light of which ones here are playing the part of grandma. Can't hear. Can't think. Pretty much potato waiting for the reaper. What I don't get is Tom why are you wasting your time with these losers? Surely you have better things to do. I sure do. Bye! |
That is not how design patents work. You either have a design patent, a utility patent or both. You said design patent and again I found no links. Design patents don't protect the function: From USPTO

@danvignau - thanks for the link to the article, I've not seen that before. The fuse he was talking about was in the speaker circuit, not the power circuit.+1 @audio2design. The text on page 6 refers to protection of the amplifier outputs i.e. the signal that goes to the loudspeakers. There needs to be protection at this point in case a fault in the amplifier sends DC to the loudspeaker drivers, which can result in quite spectacular failure. Loudspeaker protection needs to be very fast (milliseconds) which means any fuse would need to be rated very close to the maximum operating current of the outputs and it would heat up in normal use creating distortion. Most (if not all) amplifier manufacturers use alternative methods to protect the output... I use relays, others use transistors etc. The fuses that most people in this thread are referring to are power supply fuses which will not heat up in normal operation and can be rated with comfortable headroom above the normal operating current. These do not form part of the discussion in the article. |
Shear is in all shapes and materials just look around. You are blind to sound even when its in front of you. Think of that ugly reflection in your mirror and how that surface feeds back sound. Electronics can not overcome poor choices of material shapes and boundaries. Better choices come first. Only the magnets are plated. For 1 of my patents I remove material to add more reactive materials to make the device operate at its prime resonance point of contact. So by broad definition, the contents of the device are plated over. Shallow plating applies to your imagination. Tom |
So 2 design are you say I am lying ? Rod magnets are about as cheap as the wine you drink, 2 bucks each. Set up your own demo and listen in the room or close the door and go into an adjacent room and listen or go to the bath room you will be able to hear the difference over those noises also. Well in your case maybe not. Tom |
Nonoise that is a silly position to take. The fuse literally just an extension of all the wire in the transformer. There is no node in between. This is much different from the "miles of wire" before the amp argument as all there is a node where all the units connect together as well as a case grounding node and the potential for ground / neutral interaction. A fuse is just an extension of the wire in a linear supply transformer and perhaps some resistance in front of a switch mode (rarely a bad thing). Attempting to equate these two things only shows your lack of knowledge and proves my point about who advocates for fuses. |
I did the fuse and magnet demo for my they don't care daughters and 2 grandsons. They couldnt understand why others denied hearing any difference when it was so huge to the 4 of them. The 9 year old grandson described those that say they couldn't hear a difference like that of him trying speak to his 91 yr.old grandmother standing at her face and speaking very loudly..nearly deaf. Tom |
Fuses feed into 10s or more feet of wire in a transformer and high inductance. Conveniently forgotten.So do power cords and anyone with a working set of ears can hear the differences they make. All this wire after the fuse is just another variation on the old, all those miles of wire before it gets to your outlet BS: another red herring. All the best, Nonoise |
audio2design1,015 posts02-12-2021 5:27pmWhy oldhvy because for all the bs about an amp just modulating the power supply, the reality is what makes for a stable supply and the properties assigned to audiophile fuses are not the same. It’s all a smoke screen of ignorance. <<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>> A fuse that increases in resistance as it heats up (more current) would make for a more stable supply voltage. Yet people go gaga over low resistance. <<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>> I just like the way it sound, nothing to do with anything, Scientific. LOL Mercy That last part of your statement, lends it’s self to a previous comment about a twisty flat 99.99 copper flat ribbon, with .0X increase per meter resistance. It is not just R, C, and end load, is it? That silly little filament, yea buy the cheap one, by all means Recycled German cars make better fuses than recycled Korean cars.. That’s all I’m saying.. :-) I’ll stick with my 6-30.00 fuses and my FREE SR fuses.. YES I use Busman where it sounds no different. I sure would have liked to work with some of you fellas’. I personally like breakers, or bypass the fuse all together in stereo gear, or speakers (they always go, speaker fuses) I’ve NEVER had a problem. BUT I've had GREAT success with speakers and shi$s fuses in the path. Infinitys ALL OF THEM. I've owned LOT of them. YET I did a speaker cable drop that blew up all kinds of stuff. The 20 amp main breaker blew, but not the 5 amp slow blow in the VTL or the Mac 275. The stupid class d, never missed a beat. Two months after that, the Mac C2500 Pre lost a right channel. A cable drop... The ONLY one I’ve ever had, 15K if I would have just replaced the components. The busman did not blow...in ANY of the pieces, all failed. SAFTY??? 3 right channels!! That is the exact reason I tried SR fuses, I though what the heck, I was using ACME, and Tuners. They sounded better in my (Samra) C20. I used a FREE SR FUSE.. LOL BTW want to buy a pair of 300 Deluxe VTLs, perfect except the signal caps are burnt off circuit board.. Busman fuses, ay? Safety? Nothing safe about them as far a equipment. Especially slow blows. Friggin’ junk. Mechanic NEVER use them EVER... Breakers ONLY, or standard fuses, some fast blows.. (Computer fuses). Like I’ve always said, "Stereo equipment is NOT rocket science", it is really kind of simple, compared to a modern day piece of equipment. EVEN a friggn lawn mower is more sophisticated by design.. WAY MORE or mower. LOL Regards |

That is what happens when people who don't understand amps and power supplies make conclusions based on suggestion. |
When they build an amp. or pre amp or what ever, aren’t better components, BETTER?. Look at the copper foil resistors, I thought WIMA caps were the reason for the great but reasonable cost of HIGH quality sound... It’s not, it the resistors.. AND they do make a huge difference in SQ.. SO WHY are you so resistant to a damn fuse... Beyond me.. I don’t get it.. Every time I use this fuel my car does this.. OK, do you like what it does? NO, pings like a pong! Sounds like it’s gonna blow up... Answer. don’t use that fuel. BUT I use this other fuel and it runs even better, same octane. What do I do.. REALLY? oh by all means use the crap fuel... I dunno... maybe I’m just too emotional.. about the whole thing...LOL Go hug my speakers... They know they get the best... Regards.. |
