Default How to determine the fuse value

Hi friends,

One of my devices (my DAC Counterpoint DA-10upgraded by Mike ELLIOTT) has fuse on which there is no Ampere value. The only written indication is :

"250V BUS AGC1"

How I could know the ampere value of the fuse ?

Thanks

this is pure guesswork.

I think BUS is the manufacturer. Short form for Cooper Bussman.

Look up the manufacturer datasheets and see what they have to say about agc and agc1
C could be the fusing time like MCBs are A, or B, or C rated

Examine very carefully both end caps (with a magnifier lens): sometimes the marking stamp is worn out and this results in a barely visible marking.

Data sheet is here:

It is a 1A fast-blow fuse.
