I have a reissue jcm800 and it blew the T1ae fuse. Pulled the fuse and its a T1al? The nomenclature says T1ae. Is there a differance?
As long as it is a T1A and the correct size it will be fine, the lettering relates to the type of fuse and the way it will blow when there is a fault on the amplifier.
If the amplifier has blown the 1amp fuse this may have been caused by a faulty power valve and we recommend you have the unit checked by a qualified engineer.
