A singer I know gave me her Mackie mixer to repair. She uses a condenser microphone instead of a dynamic microphone. (Someone told her she should use a condenser microphone. Well I figure that she will drop the microphone and she will be back to using a dynamic microphone.)
So the problem was no phantom power to power her microphone (yet another disadvantage of condenser microphones). So I loaned her my two channel mixer and took a look at her mixer.
I was expecting something wrong with a voltage regulator or capacitor. The taps of the transformer all worked. I checked the switch and sure enough the switch was not working. BTW, on this model the switch is located on the back near the power switch and does not have an LED indicator light (dumb design). So the good news is it was an easy repair by replacing the switch. The bad news is I had to remove and reinstall about 100 screws, knobs, nuts/washers, etc. but I got it working.
BTW, I used a plastic rocker switch that I salvaged from a computer power supply.
