The proper fuse for your amp would be a Littlefuse type 218 series 5 x 20mm in the amperage stated on the back of the amp.
A fuse like this can be had from Newark electronics part number 26k8060 for a 4 amp fuse.
One thing to note hear is that a fuse in a tube type amp does not blow out for no reason, you likely have a bad output tube that took the fuse out in the first place!
The way to check this if you choose to not take it to a tech is to pull all of the output tubes out , install a new fuse and then re-install the output tubes one by one until the fuse blows again , then you have found the bad tube.
This of course means you will need a hand full of new fuses to test with.
In a pinch you can use a fast blow type fuse rated at 1 amp more then what the amp calls for in a slow blow type fuse.
