NEVER replace the fuse of your strobe other than with the recommended ones by the manufacturer.
This is what happened when a 6.3A fuse was used instead of the recommended 5A.
(inset: blown fuse)
This particular strobe has been giving me problems with the fuse, so thought of using one with different ampere rating). There was a buzzing sound and suddenly the whole strobe just exploded with a loud bang. luckily the shrapnels were shielded by a cloth and ricocheted off the fabric.
you have been warned!
