Title: Fuse questions
Post by: Maynard on August 29, 2014, 01:01:19 AM
Hi just wondering can I use a t3.15 amp fuse in the crack? I can't find the one that came
With the kit. 5 amp fuse I think. The fuse I have is a 250v one like the one provided with the crack

What does the parts list say that the value of the fuse is?  I doubt it is 5A.  Best to check, I thought it was a half amp.

It is best not to put a fuse in that might be 10 times the manufacturer's rating.

Radio Shack used to stock those.  Maybe they only stock cell phones now.

Hey you say 1a fuse but manual says .5 a will this matter?

You can choose to believe the human being who puts fuses into Crack kits (who also shares a desk with the designer of the kit), or you can choose to believe a piece of paper that may or may not have been updated.

We discontinued the .5A fuse when the Crack was the last kit to use them.  1A works just as well and is a whole lot easier to find.

That's not quite right, Paul. When I started packing, the Crack was on 1A and the Seduction was on .5A (and we still have a bunch in the packing room). It was my assumption that they were popping in the field, much like how we later switched the BeePre from 1A to 1.5A.

Hmm, yeah, now that I think about it, there were a few 0.5A fuses popping here and there.

I received my CRACK KIT last month and  the fuse that comes with my kit is .5A........

We reserve the right to change the value of the fuse sent based upon the actual performance of the batch we currently have in stock. If .5A fuses work we use them. If the ones we receive don't really hold up to the first startup surge then we switch to 1A. That initial startup is where a few .5A rated fuses have blown for customers. It is usually the highest startup surge the amp ever sees since the caps have never been used before. Either value protects the amp just fine when it holds up through the initial power on.

There is a 0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000001% chance that a Crack shipped in the last month had a half amp fuse in it when it left BHHQ.

No problem with mine (.5A) but that 0.000000000000000000000000000000000000000000000000000000001% is in my kit. ;)

After seeing your above post it reminded me I added a couple of silver hifi  fuses out of curiosity to a order for some other bits and pieces a while back so I dug one of them out and put it the crack not really expecting much and I am actually quiet surprised and not to sure about what I am hearing having only listened to a couple of tracks so far. For $2 a pop they are not exactly high end designer fuses and are a inexpensive enough way to test the waters.

There is a 16 page thread on Headfi on audiophile fuses as people discuss the various sonic differences between brands while "fuse rolling". If anything its an entertaining read...

Was tempted to ask if any of them remembered to change the fuse on the other end of their meter long IEC cords :P

I've tried some of the fuses discussed in that Head-Fi thread.   Mostly in my W4S DAC2. 

That eBay link looks quite interesting.   Thanks for the post.  Might have to buy a few and put them in a vintage Sansui and Marantz

In some gear a fuse can make a difference as can a power cord.   I use modified Shunyata Venom 3 power cords throughout my system.   Have one modified and set aside for the Crack (should elves come in the night and finally assemble it).

I never believed in either one of them.  Fuse or cords but hearing is believing.  I know it may be hard for some folks to believe a fuse can benefit the sound of a piece of gear, or even a power cord. I was the same way.

One of the reasons I like this forum is because folks believe and know that capacitors can change the sound.  I know so many folks who do not.  In all the time I worked in television I  never met one video engineer who would ever believe a capacitor can help determine the voice of a piece of gear.

Forget about hook up wire 8)
