What is the value of a Yaesu FTDX-400 with a faulty power supply?

I was listening to amateurs on 40 metres SSB when there was a bang
and the whole thing started humming and then the power board CB
popped. So something has shorted on the secondary side of the
power transformer, but it was receiving just before that happened.
I discovered the fuse had been replaced by one way overrated
so I'm wondering if the correct one had been blowing.

I have not attempted to test the transmitter as I do not have a
suitable antenna or dummy load.

I'm thinking only enthusiasts would want such an old radio and
they would be prepared to fix minor problems.

I paid AU$100 for it including a microphone and freight from
an online auction not eBay.
