on Monday morning 7/11, we tried to restart the Alphanov amplifier which was not turned on since end of april 2022, but it didn't start.

we did a standard "turn ON" procedure :
- check the safety button on the front panel (which has to be released).
- switch on the black switch on the rear panel.
- push the green button on the rear panel
- turn on the key on the front panel
- push the start button on the front panel

normally after switching on the black switch on the rear panel, a light shines in between the red and green big button on the read panel.
but nothing in that case. we just ear a weak "rotating fan" noise coming from the inside of the rack.

normally, after pushing the green button on the rear panel, the start button on the front panel comes to blue.
but nothing in that case.

normally, after pushing the green button on the rear panel and turning the key, the start button on the front panel comes to red.
but nothing in that case.

we tried anyway to connect the amplifier with a computer, just in case of...
but the Alphanov software is not able to connect to the amplifier.

One possible issue could be a dead fuse inside the black ON/OFF switch on the rear panel => one has to check it !
