wd40 into a switch? I hope that's the dielectric electronics cleaner your using and not the old school WD40 ah lubricant (cleaner really), that's not a dielectric and not good for electronics.
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?
