The hum was traced through schematics and community help to a failed electrolytic capacitor on the +22V rail, placed by the manufacturer directly behind a heat-generating bridge rectifier and rated only 85°C. The bulged Nichicon capacitor was replaced along with other similarly under-spec'd caps using 105°C rated electrolytics, fully restoring the receiver. ## Full article daily.dev links to this article rather than hosting it.
