Audio Grade fuses


I dont know much about the fuses, so I need a little help.
I have been reading a lot about the Isoclean audio grade fuses, so I looked at my Myryad amp fuses which says "T3. 15A" But I couldnt find the same number on the Isoclean fuse website.

All they have are Sizes: 5 x 20mm (.2" x .79") 1A, 1.6A, 2A, 2.5A, 3A, 4A, 5A, 6.3A, 8A, 10A...But my original fuses are also in 5x20mm, but it is rated at 15A, so would I be able to replace them with the Isoclean?

I use the 3 amp Isoclean fuse in my Fisher 500C receiver which originally had a 3.25 Amp fuse.
I recommend a 3 amp fuse, not a 4 amp, where the original value is 3.25 amp. It is prudent to err on the conservative side.

To the naysayers: Don't judge a product until you've tried it. The new ceramic fuses from Germany are a significant upgrade. The improvement is very similar to replacing your stock wall sockets to the after market high end wall sockets. We're not talking subtle improvements here at all. You will experience a much lower noise floor and the resultant advantages of that.
