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?

It stopped reliably turning on. When it would turn on, it would work as intended.

Sounds like a bad power switch. 

"Sounds like a bad power switch. "

Well, now! Who else might have suggested that?? 🤔

Based on descriptions given earlier, sometimes the amp comes out of protection, sometimes not.
