Did you try a different power cord that is known to be working?
Integrated stopped working
In 20 years of hifi, I’ve really never had issues. Until today. I’ve been using a Micromega M100 for almost a year. Today, it won’t turn on. Nothing has changed between today and yesterday. Just won’t turn on. Checked the fuse, it’s good. Checked my power source, it’s good. There is no hard turn off. Just the standby button. Any thoughts?
