Hi guys, Well we've been here before but this time things have worked out for the better w/ a twist. I used to have a refurbished old Sony fake wood w/ glass front rack which was starting to fall apart. Since some of my gear is rack face mountable I built my own rack.Off to Home Depot I got so angle irons ,L brackeks,hardware and some wood for shelving.This time when I derigged I labeled everything so no mistakes would be made like the grief I had and
talked about many times. The rack gets fastend things get plugged in and now I get t hum that was as loud as the music. This is driving me nuts, nothing was touching the steel that shouldn't no shorts and no grounds ,so what gives.Then I started the old process of elimination and to my amazement and surprize it was the HDMI cord going to the cdp. Why, well that's for you guys to figure out but thankfully I have an optical lead going from the avr the cdp.
I know the quality of the cord wasn't the best but it was a very short one.
If I get another cord and the hum is still there then we have some other issue. Thanks for looking and here's my rig in it's entirety.....
