Fuse : Voltage ratings


My AES SuperAmp 25 has company supplied Fuse of 250 V, 500 mA. I ordered HiFi Tuning Silver Star Fuse 250 V, 500 mA as a tweak/ upgrade for my Amp . What I got from the supplier a Fuse of 500 V , 500 mA. Is it safe to use this 500 V fuse to replace the 250 V fuse ( with same rating of 500 mA ) ?
Considering the cost of the Fuse , I wish to know from guys here before I even try to install the new 500V Fuse.
Thanks

Both Fast and Slo-Blo are available, in all of HI-FI Tuning's versions. ( http://www.partsconnexion.com/fuse_hifituning_main.html ) YES- NEVER replace a Fast-Blo fuse with a Slo-Blo. Damage to your equipment could easily result.
Howdy folks,
Not exactly on topic, but close; has anyone had problems with the 2 amp AC fuse blowing on the 25? Mine went for no apparent reason and I cannot see anything inside the case that looks out of the ordinary. There is no sign on any component that would indicate a problem. I have just ordered 5 new fuses so will be trying one out when they arrive (couple of weeks, unfortunately) to see if it blows immediately or ??
Any experiences like that?
