Quick fuse question

I can't say I am a proponent of fuses but those were rants most definitely. Reading a certain incensed persons interesting and quite wrong views on a number of topics I don't think they should be calling others technical Luddites.


Let's start with that whole AC argument about fuses. That is a factually wrong and circular argument. Fuses are not directional because their transfer function is independent of current direction unlike say a diode. Of course those promoting fuse direction usually without knowing it are claiming that the transfer function is dependent on current direction hence the whole circular and wrong argument of "it's AC". Luddite is all relative to me someone who uses this argumemt is a Luddite. Think diode and try that argument again.

Like I said no idea

LOL I got a great idea. With my little experiment, I proved to myself that the fuse circuit inside a lot of older amps in particular, really limited the amps ability to work propper.. I NEVER had a failure that took out an amp because of a fuse, being moved. I have seen time reset fuses burn equipment to the ground though.. Usually and oil leak, dirty dusty lent and a fuse resetting. You do have to be carefull.

Stereo equipment may seem expensive, when it takes a dump... But there are a lot worse, equipment failures, than stereo gear.

A lot of the new equipment 1/5 the cost of making the things work is digital/analog. 250,000-2.5 million burn to the ground.. FUSES, big dollar fuses..... not run of the mill fuses. Like my buddy George... THINKS..

The world is a LOT bigger than stereo gear, George... Where do you think the ideas for super duper fuses came from....Silly fella...Stereo gear? Not even close....

It came from a need like being in space, or in a tunnel full of coal dust, medical equipment or because something else other than STEREO gear.

Funny guy George.... See no name calling.. just a funny guy...

Regards...

Like I said no idea. 

Anger issues coupled with a lack of knowledge. Charming.

Fuses of the same current rating can vary 5x or more from the lowest resistance to highest resistance at the same operating current.

Perhaps someone without anger issues and potty mouth would like to answer my questions.

if I put in a fuse with higher resistance

You guys have no idea, it’s the resistance that causes it to melt and blow, 🤦‍♂️ go f*****g around with that and you’ll blow your equipment instead, that’s why it’s called resistance wire inside a fuse, if it didn’t resist the over current and blow, your equipment would be toast! leave things alone you have on idea about, really🤔

Now apply that same analysis to the fuse in a pre-amp or DAC.

Next, tell me, if I put in a fuse with higher resistance, will there be less or more noise on the output of the amplifier power supply, and will there be less ripple or more ripple?

I know this, I have removed the fuse circuit a few times, and welded silver conductors, not soldered, WELDED, Silver wire to a silver dipped spade, via, joining the two with 99.99 9 silver... BIG difference, in sound..

Not the wisest move, but it sure proved a point to me. James B of Ampzilla, told me he was tired of the Power Cord debate (I didn’t know there was one at the time) I was working on the generators for the CES show, and a few other conventions, while construction was going on.. (always)
They were big cat gen sets... I knew him and Brian C of VMPS and Doren Dibble the Cabinet guy... That was a smart guy... He sure believe in a GREAT Power Cord.. 25 years ago.. He WELDED his PC into the newer SST. He was the one that told me FUSES were a problem, just like Power Cords... He made and designed the thing. Enough single malt he’d build one for you, out of silverware... Smart cookie...

2004-8 He welded his PC. I think they still make them the same way...
Serious amp.... 2000 series... That thing doubled power down to 1 ohm.. maybe 1/2 ohm... from 50 wpc @ 32 + ohms. (?) FUSES can be a big problem with 1/2 - 1 ohm loads, I assure you...Fuses need to be secured TIGHT, a little spring loaded fuse holder won't work. LOL BUT they will catch on fire... TIGHT.... Graphene paint sure helps too.

You call them rants, they are facts which fuser refuse understand, that’s why it’s considered "snake oil" all over the industry by anyone with any cred.

Your "grand fuser poohbah" geoffkait who is strangely absent these days, is proof of the kind that is attracted to the fusing cult, even his avatar is a voodoo doll
His audio snake oil web site https://www.machinadynamica.com/machina5.htm
just one of his snake oil products https://www.machinadynamica.com/machina31.htm

George, do all of your insane rants give you some sense of validation? Is this what amounts to accomplishments in life for you? You need to get a hobby as this one is just not working out for you.

All the best,
Nonoise

P.S. I did notice a difference when I reversed the fuse.

And there it is (an upgrade to grand fuser), ac mains (alternating current) changes it direction 60 x a second (60hz) think about it?


The gullible need both sides, so they don’t get shafted with spending $$$$ for a 50cent fuse.

@georgehifi You are a JOKE my man! Hopefully you can get a life and stop with you bashing. Maybe you can find some solitude listening to your Walkman/ Beat Audio headphone system. P.S. I did notice a difference when I reversed the fuse. Have a great life georgehifi.

Anyone, that pushes $$$$ ac mains fuse to the gullible like we have here, are in my sights to keep a balanced technical perspective on this snake oil.

George, you should see someone about your PTSD. You're nothing more than a stalker. 

I'll bet that you've added mktracy to your hit list and will pounce on any future posts he makes like you do to others. Maybe Admin should give you a time out.

.@georgehifi Thanks for you unhelpful comments

Your welcome.
Your now officially one of the "fuser gang" junior members, once you have mentioned just how much better an AC mains fuse can sound reversed, then you’ll get promoted to "grand fuser" status🤦‍♂️

@mktracy  You're very welcome. 👍

@rodman99999 Thank you very much. georgehifi doesn't faze me seen him around always bashing on people just because he doesn't believe in something. Maybe he needs a more resolving system and get rid of that Crosley all in one.
@nonoise Thanks for the help with the naysayer georgehifi. I trust my ears and know what I hear on my system.@georgehifi Thanks for you unhelpful comments. I didn't realize that you paid my bills and knew what was best for my system. Ive been in the industry for over 20 years and I know when I hear a difference in sound with my system. If you don't believe in fuses, IC's or PC's then that's your belief but many people do. So next time you don't have anything to add to a convo that's helpful just sit back and content yourself. Also THANK YOU for having my discussion moved to the land of the lost. One day you will learn to mind your own business.

Oh, the wit!
The only time **** happens is when you butt into the grown up conversations.

Any bets on how soon these two posts are removed?

With the **** you talk about fuses, I would say soon 

More like the Blunder From Down Under.
Any bets on how soon these two posts are removed?

Also, when have I ever shilled for SR?
You're such a goof. Too bad you post here,
waiting to pounce on people for imagined slights
when all it is, is your over inflated ego.

All the best to my sundowning friend,
Nonoise

Appears: you’ve got things covered, mktracy.     Nice gear!      I really enjoyed my ARC pieces, back when.      Just ignore anything The Wonder From Down Under posts (OCD/mental constipation/digital diarrhea).

 You just went and cried to the mods

Of course I did, I didn't say otherwise, as soon as you or your "fuser buddies" come on and start shilling for SR 😴

You don't fool anyone, my insecure friend. You just went and cried to the mods and had my post removed, like you've done before. You're not that clever, by half. How else would they know of such an unimportant matter in so short a time?

All the best,
Nonoise

I don't do it admin does sunshine🤦‍♂️ and they just move them to the appropriate topic forum. Just like they just did with this one 👍 

George seems to forget that we remember his bragging about getting several fuse threads shut down. Typical George.

You can always count on George to troll away and try to get another fuse thread deleted.

Really! had a mirror to see what’s looking back🥴
BTW it wasn’t deleted, just moved to the appropriate topic forum, if you bothered to look troll.

Thanks. Ill check out the HI-FI tuning fuses and see which one I prefer.

Don’t, you’ll just be shafted with it. Just get a $2 Bussman fuse the correct amperage for your needs.
If you want to be one of the gullible fusers, go to this thread that got relegated to the "Misc Audio" section, and where this one (att admin) should have been started, there could be the need for a "Rubbish Bin" one also.

Cheers George

@rodman99999, Yes I have played with IC's and PC's. I have a ARC LS25mki pre,D200 amp and a PH3 phono stage and a Teac VRDS25X CDP. All IC's are Audioquest Sky XLR except the PH3 which are Audioquest Viper RCA. All PC's are Virtual Dynamic Nite 2's except PH3 which is using a Acoustic Zen Tsunami 3 PC. My speaker cable are Audioquest Mont Blanc 8ft pair to some modded Magnepan MMG's. I love the way the system sounds but never thought about fuses before, have changed all IEC connectors to Furutech FI-06g and that made a difference and then I started playing with fuses. Again thank you for all the info and help and Im really enjoying the music!

I get it, mktracy.     Like I said; peace of mind is important.     Since you’re able to discern the differences fuses make in your other gear: have you experimented with upgraded interconnects and power cords?     There’s aural gold in those, depending on your choices, without risk of damage.         Your welcome and ENJOY YOUR TUNES (all that matters)!

@rodman99999 Thank you for all your help and info. Im going to stick with the stock MDQ fuse and just deoxit and clean it up. Dont want to take a chance on not having protection on the amp.

Have fun/happy listening!

@rodman99999 Thanks. Ill check out the HI-FI tuning fuses and see which one I prefer.

Got it (I thought the Bussman came out of another component).     If I’m not mistaken; the Silver Star’s been discontinued, though some dealers still have a limited inventory, on sale.    I had used the Classic Gold, for years and liked them.      Skipped the Silver, when the Supreme came out.

@rodman99999 , I will try the AMR 6.3A and see what happens. The 5A Bussman was new and never used though. I heard good things about HI-FI Tuning, but most people seem to like the Silver Star better. Any thoughts on the differences between the 2 HI-FI Tuning models?

I'd try an AMR 5A, Slow-Blow and see if it holds.      The 5A Bussman may have been old and compromised/weak, from however long it had been in use, prior.       If a 5A AMR won't hold, through a normal start-up; your amp won't hurt itself with a 6.3A.           If that holds and lasts a while, go for a HI-FI Tuning Supreme.     They make both 5A and 6.3A (you may already know).      I like 'em!

@gs5556 Thank you for the info.@rodman99999 No the Bussman 5A was just a regular Slow-Blow 5A fuse. Not sure what brand the original MDQ5A is but it is back in the amp and works fine. So guys is it safe to say that if I put a 6.3A boutique fuse (AMR fuse) in the ARC D200 that it will be protected and work fine. Or am I just out of luck with using a audiophile fuse?

mktracy-    Was the Bussman 5A a dual-element?     If a single wire, twisted around a small rod, it was a Slo-Blo.        There’s a difference in time and function, between those two designs (see, "Selection Considerations" and, "Fuse Characteristics Curves and Charts", page 6 and on, in the link below).     If a higher value seems too great a gamble, but- the only recourse (far as an upgraded fuse); that stock dual-element must remain.                 Peace of mind’s important! https://m.littelfuse.com/~/media/electrical/application-notes/powr-gard-technical-application-guide....

Dual element fuse sizes are selected by different maths than the typical fuse. The ARC fuse is sized closer to the overload trip than the short trip. Single element fuses only do shorts. In this case, the overload trip is the fuse rating and is 5 amps and the short trip is, I dunno, 7 amps. If you substitute a 5 amp single element it will trip since 7 amps is coming through on inrush.

@rodman99999  they are made in China but they are they same as AMR fuses from the UK. I really don't just want to place a higher value fuse in the amp. The original MDQ 5A fuse still works fine, the 5A standard fuse was a Bussman that I had from another component and it blew. I was going to get some HIFI Tuning but dont want to just through money down the drain if there not going to work.

OK! Those fuses are made in China.     Even the high-Dollar, high-end (or whatever one deems them) fuses, from HI-FI and Synergistic (not certain about any others) will typically require a slightly higher rating, than stock.     Don’t ask me why!     That’s their recommendation.     It’s what I’ve encountered and have had no issues, with the (slightly) higher rated fuses.     You could try a 6A (a 20% increase).     I suppose: some would call it gambling.                     Then again: those from China are relatively cheap.    Try a few more of their 5A fuses, first.    Your original may have been a lemon.

@rodman99999 Yes, put the original fuse back and amp works fine

Did you try it again, with the original fuse?    I just downloaded the manual.   Not really familiar, with your amp.                OK! I’m guessing that you mean the, "protect" LED lit, during the amp’s start-up, then the fuse blew.       Did the protection LED seem to be lit any longer than it normally would?      I ask, because a fuse wouldn't cause that.

@rodman99999 , I used a Slow-Blow 5A. I turned the amp on and it went in to its normal protection mode then shut down. looked at he fuse and it was blown.

Was the fuse you tried Slow-Blow or Time-Delay?      I ask because: a Fast-Acting, 5A fuse likely wouldn’t last, in the place of an MDQ (Time-Delay) 5A.
