Fast/Slow fuse?

I was looking for two kinds of fuses, one slow blow (10A, 250V) and one fast blow (4mA (?), 250V). Went to RadioShack and found that they had fast blow type fuse for 10A/250V and slow blow type for the other.
I just bought them anyway.
What would be the worst possible problem of using fast blow fuse instead of slow blow fuse, and vice versa?

If you need a slo-blow a fast blow will burn out when the device is turned on. A slo-blow will not protect a device that calls for a fast-blow. You should always use the type of fuse the device calls for.

Rwwear is right! Don't do it. You can get by with lower voltage fuses temporarily I believe but get the right ones. You can cook your gear.

Also, if the amp blew a fuse something bigger may be wrong any way.

Thanks.
I just wanted to check if the amps work, but I could not find right type of fuses.
I tested my amps with those types, and at least found out that the amps work!
I am not going to use those fuses any longer and will order correct types right away.

Any REAL electronics supply house, in your area, should have the correct fuses for your equipment. Check your yellow Pages under, 'Electronic Equipment & Supplies'.
