Hiwatt Bulldog 30r Which fuse is right?

[frank57]

So this amp blew a fuse yesterday. Not sure why, but it was cutting out the day before.Resoldered the jacks and turned it on and phfft.
The schematic says slo blo, but does that make sense for ss amp?
What was in the amp all these years was apparently F 1 al 250v instead of T1.6al 250v.

It is no problem to use a lil smaller fuse, but do not go higher than the specs.

turned it on and phfft

Fuse still blowing?
