Re: Tron speaker hum after MCR adapter for switching ps....

HPF= High ?? Filter, is that right? What exactly are we talking about? I've tried chokes, caps, and coils of some sort with no luck. The person that finds the one-size-fits-all solution will be blessed with beer from me.

Your talking about a HPF on the power input right? I think you would
have to cut the frequencies pretty high to get rid of the hum I've
heard from some MCR games. Seems to be from pretty low to well into
mid-range levels.
