My DK Jr. has a slight wave, and I just realized that the power cord has no ground
I've got this DK Jr. (now a Mario Bros) cab, that has always had a slight vertical instability. It's just a little wavey, nothing too noticable. I've had various PCBs in this cab and the wave is always present. My B+ appears to be stable at 108.1.
I did a search on here and found that grounding could be a possible cause, so I started poking around and it looks like somebody removed the ground from the power wire that goes from the cab to the wall (the ground plug at the outlet has been removed and the green wire on the cab end does not attach into the power wire either.) Everything else in the cab appears to the wired properly.
I looked at my DK for a cross reference and it has the 3 prong ground plug and everything is fine with that, no waves, rock solid monitor.
My question is, is there a way for me to safely hook up a ground to see if that fixes the issue? I don't want to electricute myself.
