That has been called the "smoke test". Replacing a blown fuse with a much higher value will often result in the defective part going up in smoke, however it may take other parts with it.
The only place I would risk it is in the amp. Speaker fuses especially. The damage is done by the time it blows anyway, so I hear. I've not blown an amp fuse in 35 years and done lots of experiments. I would not mess with stuff further up the chain, though.
