I believe so that its a slow blow but will confirm if it isn't. I did notice the first time it blew it had a 3 amp and thinking of maybe replacing with a 3 amp instead of the 2.5's currently being used. Dunno if this is a wise move??
I would use the rated fuse - a 2.5 Amp SB. Fuses are in circuit to protect components, and it is the weakest link in the chain. If there is a problem, you want the fuse to blow !
