1 amp fast blow.

Thanks for your help guys appreciate it I ordered some off of Amazon 1 amp fuse. Yes there's a little sliding door that pops out in the back that holds the fuse and the spare fuse there was no spare in there so I had to get some from the Amazon.
I bought this off of a guy Facebook Marketplace that lived around the corner from me I gave him a hundred bucks for it as I was arriving at his house he plugged it in to make sure everything was good and he says the fuse popped. From what I've read it could be a tube issue could be a short inside somewhere. Do the headphones need to be plugged in when you turn it on can that cause a fuse to blow?
