FUSE Question...Very Confused Please Help !

I have a Ceratec Penta Amp ...Made in Germany.

The installed fuse that came with the unit is rated @ 250 Volt / 5A

The Fuse Holder which is under the AC plug states "USE ONLY 250 Volt Fuses."

On back of Amp there are a choice of two fuse ratings:

#1. AC 230:S2.5A

#2. AC 110: S5A

I have it set to #2 setting ....AC 110 : S5A

I am confused. Is this fuse correct ?

Thank you

The designer of the amp only bumped the fuse up 110%. 4.55A X 110% = 5A. A 5A slow blow fuse seems a little tight to me for the amplifier... 500VA / 230V = 2.18A X 110% = 2.4A (Round up to 2.5A.) (500VA / 120V = 4.17A X 120% = 5A) .

The obvious (against sarcastic) answer is: real audiphiles replace any fuse with 6 inch nails that have been cooked in double extra virgin oil with vinigar for 2 hours and then powdered in pixel dust (the mega pixel variety).
