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?

I was too anxious and inept to do it correctly

He was recommended to me years ago by another poster here. When Kris is done, he contacts me. Creating a time constraint for a tech is not something I would do.
