amp I bought 3 days ago not powering on - electrical engineer advice wanted

I bought a used Musical Fidelity A380 in good condition. Played it every day, worked fine.

Today it did not turn on. There were no sign of failure yesterday. Could it be a fuse or power supply?

Update: my troubleshooting is shot. It doesn't turn on now when nothing is plugged on. All my hopes are in the Murietta tech baby!
