DR #52 - Speaker Amplifier Repair - Definitive Technology CS-8080HD 

I was sent 3 Definitive Technology speaker amplifiers for repair. In this video, I repair the CS-8080HD center speaker amp. Most of this video is centered around investigating and repairing the amplifier's switching power supply.
You'll see troubleshooting using a multi-meter and self-made block diagram, parts replaced, and final testing using a signal generator and an oscilloscope.
