Yamaha M-60 Blows Internal Fuse

I've had a faulty Yamaha M-60 sitting in my stack for quite a while and have just had a peek and can see that the first fuse is blown. I've had a look through some past threads, but cannot see anything obvious.

Is there a usual reason that this fuse pops, or could it be anything?

Thanks

I’ve measured these two rectifiers ‘D5FB20’ in circuit and they measure oddly to me (both differently and the same both ways) so they may well be blown. I’ll pop them out and remeasure if that helps.

Do you know of a suitable replacement part?
