I don’t often get studio equipment on the bench, so this Presonus repair was a new one for me. The customer was finding that the unit buzzed uncontrollably on all outputs. Experience leads me to test the internal power supply when a noise problem appears all over the unit, in this case, my hunch was correct and the repair was finished in a couple of hours.
Update June 2023: After a few enquiries, I’ve made a DIY capacitor kit available, so you can fix your monitor station yourself. The product info is here.
