Alesis QS6.1 output hum

2015-11-12 by arnaldo.ortega@...

Hi All,


I have an Alesis QS6.1 that developed a subtle but annoying hum in the audio outs (main and phones) after around 10 years of good service. I'm suspecting of capacitor malfunction in the power supply.


Has anyone ever serviced the power circuit capacitors in the QS6.1? Were you able to eliminate the hum by replacing them?


Thanks,

~ACO
