Standard US Type fuse
 

Hi Sergio,
That is a US standard 3AG size.
It is 1/4" diameter and 1 1/4" long.
Very commonly used before the metric fuses became popular in the US.
Converted to metric it would be a 6.35mm x 32mm.

The "AG" means auto glass. These were typical in American cars years ago before the blade type now used.

You can easily order them on Amazon. As an example, here's a 3 amp Littelfuse 3AG Slow Blow.

Make sure you look at the current rating stamped on the end of your old fuse.

Thank you for assistance, gents! :thumbsup:

one more question:

any manufacturer who produce so called "audiophile fuse" available on the market in this type?

Sergio --- Music Direct sells HiFi-Tuning Fuses which many on AA have chosen to replace their 'stock' fuses.
