Correct fuse size?

[MK IIB]

Hi folks,
I need to order some replacement fuses for my Mark IIB.This is my first time having to do this.The amp has the export Transformer and is being used in the UK at 240V
On the back of the amp it says to use a 1.5A fuse(for 230V)The one that was in it was a 2A(250V)
Is it the 32mm I need?
Will it have done any harm having the 2A in it?
Thanks folks.

If you use a 2amp fuse in place of a 1.5amp you could have problems.The 2amp wont blow when it should and could cause something in the amp to burn before the fuse can do its job.
