m400 fuse question

First time poster.

I have a Carver M400 which has blown it fuse. It takes a 15 amp, 32 volt fuse and the back of the amp says Line Fuse AGC15.

So I go out and finally find a 15 amp, 32 volt fuse, for automotive use admittedly, and it blows two in a row.

Any help would be graet.

Thanks,

It has to be a SLOW BLOW type fuse! I went through this headache once with my M-500t back in the 80's. My 10 amp fuse had a white paper like cylinder for the body. A regular one will blow almost immediately, LMAO...
