I am restoring an old Marantz 1050, and slowly measuring, recapping and cleaning its components. Yesterday when I was about to recap some electrolytic caps, I noticed that a couple of ceramic caps seem to have a yellow discoloration at the top (picture attached).
After asking in the DIY forum whether that was a sign of a bad capacitor, they replied that it was more likely a mark from the manufacturer. Does anybody body know what those markings would mean? No other caps are marked this way in the circuit. They are C403 and C404, both 82pF.
