No, you shouldn't exceed the current rating recommended by the manufacturer. Otherwise, you run the risk of doing serious damage to the component if a fault occurs in the component and the fuse doesn't blow at 200-ma to provide the required protection.
Good luck,

Hum, that funny. Over at Tweaker's Asylum duster is recommending a 500ma fuse in a pre-amp that came with a 200ma fuse.

Most circuits have multiple components. Consider that, with a 200 mA fuse, for example, you may lose one component before the fuse pops, but still protect other components in the circuit. With a 500 mA fuse, you may still be protected from starting a fire, but end up losing multiple components in the circuit before it pops.
Since you're the owner, you can actually use any size fuse you want that's equal to or greater than 200-mA. So long as no circuit faults occur, you'll be just fine. But, if anything should happen to go wrong, there's greater risk of serious damage when using a fuse larger than 200-mA.
