FeedbackLoop | #104 - QSC K10 powered speaker repair @feedback-loop | Uploaded 3 years ago | Updated 12 hours ago
This speaker was described as "blown" and offered for cheap. The problem was traced to a shorted MOSFET on the primary side of the switched mode power supply and one dead electrolytic capacitor on the secondary side.
