Fuse : Voltage ratings

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?

Thank you guys ,
I now know that I am OK with the 500 V Fuse sent to me.

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.

Is there an issue regarding slow blow and fast blowing fuses? What kind are the HiFI Super Tuning fuses?

Agreed. You're fine with what was sent to you.

No issue with using a fuse with a higher voltage rating - as long as the current rating is the same.
