Disassembly And Repair Of A QSC RMX 1450 Power Amplifier

One day during rehearsal, one of my power amplifiers started having trouble, so I put it on the bench to see if I could fix it.
This teardown looks inside a QSC RMS 1450 Power Amplifier. It involves some cleaning, some testing, and some luck!
I also get to drag out my oscilloscope, which is always exciting!
Can I get this amplifier running again so the band can get back to work?
Let's Give It A Try!
