88/365 Can you fix it?

Or is it terminal? My 1950s Singer, given to me a few years ago by my wonderful MIL, may finally have bitten the dust. :0(

It was repaired last year by a friend and he'll see if he can fix it again, but I'm preparing for the possiblility of having to let it go. I do have an alternative machine, but this little beauty is my favourite. My MIL, Rita, had it from new when newly married and it has stitched yards of curtains and made many alterations and repairs, the box still has the original key.

On Friday the fuse went, and the replacement fuse went straight away, so its shorting somewhere. Here's hoping ST can fix it.
