Hello friends. So I made my Defy 7 work, and it sounds great. But now my vintage JP80MC has developed noise in the left channel only of its MC stage. It’s “motor-boating”, which to me indicates either a bad capacitor, or a bad regulator. On my unit regulator markings are sanded off. On later units Jadis stopped that practice, and markings with numbers are clearly visible. I was able to find reasonably clear pictures of the power supply, where 3 out of 4 are clearly seen, but not the main chassis. May be somebody knows what they are? Thank you, Mark
