You will want to make sure the VOLTAGE and CURRENT values of the replacement fuse are the same as on the original fuse. Any brand fuse should do as long as it is the same physical size and has the same ratings. Some fuses are slow blow, etc. They may not be labeled as such. Assuming these are glass fuses, you should look at the center element and make sure the replacement fuse looks the same. Better yet, see if the manual or schematic tells exactly what the fuse is, or look it up on the internet if there is a model number on it, or call the manufacturer of the fuse or the audio equipment, etc.......
