Fender Amp Can Fuse?

[AJ Shifty Jnr]

Howdy,
Has anyone replaced the fuse on an Amp Can and remember the ampage? It does not appear on the fuse...most frustrating...
Any Help Appreciated,

from the schematic

"F1 is a narrowed trace in the PCB copper. should trace be blown, replace with 30 AWG bus bar."

here is the schematic PDF also:

Dumb Down Here

Thanks Mr Q...
...but evidently I need this dumbed down a couple notches. I did my net research before posting and found that schematic...more research found the symbol for fuse...more research found out that AWG is acronymonious for American Wire Gauge...now I presume there must be formula to figure the ampage that can run through a given gauge of wire but heck if I can find it...I got a favourite tech nerd in a dusty electronic parts place, desperate for company who I know can help...but it is cold out...
Anyway...Thanks Again

hey you know more than I do then.
I studied Electronic Engineering at Uni before becoming a clown, and had no idea what AWG bus bar meant either...

...just in case anyone comes across this thread searching for the knowing...it is a 5mmx20mm fast blow 4 amp fuse...and it wasn't blown but the little springs in the fuse holder had compressed so much they were no longer making a strong enough contact......stretched them out and amp can is alive again...
