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?

The 308 might be reacting to a lower/variable amount of voltage from the wall. I would also work-in (power on/off, power on/off a few times) the particular breaker powering that outlet. I have found this to be the case on a handful of occasions in my 60 + years visiting people's homes and in my own home. MrD.
