So I got a new amp (JCA 100HDM)
Anyway, my only query is down to the mains socket cable.
The cable of my amp is for EU-style sockets but I'm in the UK

The cable that came with the amp has a 16a 250v fuse, but I used an adapter that was 13a without any problems.

So my question is, since I have a spare amp mains cable that is 13a and still 250v, is it safe to use it?
Or will I need the 16a to avoid problems?
