You might look at this...

http://www.radioshack.com/product/index.jsp?productId=2102746&znt_campaign=Category_CMS&znt_source=CAT&znt_medium=RSCOM&znt_content=CT2032234

Scroll through here:

http://www.homedepot.com/webapp/catalog/servlet/Search?storeId=10051&langId=-1&catalogId=10053&keyword=fuse&Ns=None&Ntpr=1&Ntpc=1&selectedCatgry=Search+All#/?c=1

Or here:

http://www.lowes.com/Search=fuse?storeId=10151&langId=-1&catalogId=10051&N=0&newSearch=true&Ntt=fuse

But go ahead and try it. In theory, 1A = 1A. A device that consumes 450W at 120V will draw 3.75A. The same device on a 240V line will draw 1.8A

I still say you need 1A 125V or 0.5A 250V

Thanks Art, I went to Radio Shock, Nothing, then Lowes, Nothing, Then Home Depot, NOTHING, Finally I went to a local hardware store (should have went here first) and they had a .5A 250V but not a 1A 250V so I went with the .5 250V Slow Blow. Thanks for the help I'm pretty sure my amp is now safe!

yeah, a lot of Radio Shacks do not have much in the store, except cell phones.

It still surprises me that Guitar Center doesn't stock fuses for the amps that they sell. But that's the way it is.

Glad you got your rig up and running.

And cheap, imported remote-control toys. They should rename the place "Shanghai Shack".

:evil:

I happened to notice this weekend that our local Ace Hardware Store still stocks a good selection of Buss-type fuses, both slow- and quick-blow types.

Everyone does agree that .5A 250V is the best equivalent to a 1A 125V?? Just triple checking :)

I see no issue -- the specs for the substitute fuse still conform to the "PIE" equation required for your particular application, where power ("P") = current ("I") x voltage ("E").

Two bucks for a five-pack is not a bad deal a-tall!

I'll try not to muddy this one with excess jargon...

As for the fuse rating, you need to understand the device first. A fuse is a "current-limiting" protecting device. A 250V rated fuse is fine to use. 250V represents the max voltage circuit you can use it in. The current rating (i.e. 1A, or whatever) is what you want to hold consistent to.

Basically, you don't want the current to exceed 1A. In this case, the expected surges are such that you might occasionally approach 1A, thus a "slo-blo" is used to compensate for those infrequent spurts when the current gets close.

Thus, a 1A 250V fuse is fine to use. You see original fuses at 125V, etc., because Fender wasn't such an international company "in the vintage day"...good ole USA! :P

So, don't misunderstand a fuse. the 1A, 250V is not like a 2A, 125V...a fuse is not a power-limiting device...it's designed to melt away due to "excessive current" draw. The voltage rating is given to get you into a general range...much like 12V fuses, etc.

Hope this helps... :)

EXACTLY! It's why most fuses have 125V/250V ratings. Notice how main circuit breakers, for the house, are rated in AMPS?

That's why I was saying 1A= 1A (in theory.) but then again... But still 1A=1A.

I have never had a problem finding fuses, except at Guitar Center and Sam Ash. They look at you with a blank stare. :shock:

I was out of town a year or two back and popped into Guitar Center asked for fuses while I was there and the dude is like "why would we have fuses?"

And I say (after I give him a blank stare back,) "You sell tubes don't you? You should sell fuses as well." If it is accessible from the back panel (or front panel in some models) it is user serviceable.

Freeking retards. :twisted:

It's all that "body art".

The inks used to create tats cause irreversible damage to the frontal lobes.
