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?

@thecarpathian I think devinplomber's analysis confirmed that it's not that board. The instructions travel downstream that the power is and then it is rejected by another component. 

two scenarios:

1) turns on, led on volume dial turns red in 8 seconds

2) does not turn on,  led on volume dial turns red in 8 seconds

 

I don't think I have ever bought a piece of audio equipment from craigslist. What I ave learned from this thread?  Don't change this policy.
