Musical Paradise Int Amp MP 301 MK l : A FUSE Question

I have the original MP 301 MK l .

I checked the fuse value and it reads  F 3AL - 250 volt . ( fast blow ) 

I did much research to find out if that is the correct fuse for this unit.

The MK ll and MK lll fuses are T 1 A 250 volts ( slow blow )

I emailed Musical Paradise but as yet have had no response.

Does anyone have this MP 301 unit ( The First edition ) and can tell me if you have the same fuse in your amp as I have in mine.

Thank you

in yours.
