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?

He ordered one, will receive it in a week and then complete it. I think it’s a good sign. I don't think AOC will be president, but I would be pleased if she were.

This will be the end of that type of commentary... Actually, curious how it can be the battery. What does that have to do with it powering up?🤔

I didn’t just read it or anything, it just surfaced now through the vast depths of my mind bogglingly stupendous intellect.🤓

Amps with faulty protection circuits turn on all the time. Working correctly and having stereo outputs is a different matter.
