Well, I am sure I can get rid of the hum, so then it will be all good. In fact, I know I can do that just be unplugging the PP2000. That is not an optimal solution of course.

Oh, yes, lots of them. And there had been a major construction project going on right next door, with all sorts of equipment running all the time.

Well, it sounds like ground loop hum, so I still think I just have to trace it out. I am not overly concerned.

I did have to replace a pair of interconnects that got pulled apart when I was moving the heavy PP2000 into position. That might be something to look at, since it is also a change in the system, albeit to an old pair of interconnects I had lying around.

I believe it says not to do it.
