fuse question

So ive got a speaker with a blown fuse.

power supply on speaker is labeled 10Amp 250v.

stock fuse is labled '5jf5al250v '. its a 5x20mm. I cant find any information on it

it keeps blowing the 5 amp 250v(both fast and slow) rated fuses i put into it.

My question is should I try a 10amp fuse since thats what the speaker draws? Or is it more likely a failure somewhere in the power supply itself? also should i use a slow blow or a fast?

The 10 amp is what the speaker power supply is rated to supply without overheating. This should be somewhat more than the speaker requires. So the questions are: 1/ Has the speaker been working properly and this is a new problem? If so I would expect something has failed in the speaker or power supply. 2/ Are you putting together a new system? If so the 5 amp may be simply too low so try 10 amp fast or slow.
