Fast/Slow fuse?

I've been to two ACE hardware stores and one RadioShack, but they all don't have them. I guess they are not real electronic shop.
What I want is 10A 250V slow blow fuse and 4A 250V fast acting fuse. I will go for online.

I guess using a fast acting fuse instead of a slow blow fuse may burn the fuse faster, but may not affect other electronic components. Am I right?

If the fuse is for a power amp it may not hold when the amp is first turned on. The initial inrush current for the power transformer and charging of the caps in the power supply could be many times the FLA (full load amps) of the amp. A slow blow fuse has a built in lag time for the initial inrush of current.

JEA48 is correct about the inrush current. Some manufacturers insist on blasting the current in, and the risk of blowing fuses is far greater. A good 30-45 second bleed of power in the circuit is far easier on the system, and fuses, but few do that. When in doubt, go fast blow, and get a few. Check the manufacturer request as they know the inrush current risks to the fuse. Jallen

A quick on line search did not result in any.
Some suggest that lower amp fuse may work. For example, 8A 250V slow blow fuse may work well without affecting other components.
Any idea?
thx

How about here: (http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=F2511-ND) (http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=F2647-ND) You have no actual electronics supply houses in your area? Yes- You can always go lower in amperage safely, but then the fuse may blow prematurely too.
