@mikelavigne: Mike- you preachin’ to the choir. I am also of the view that sorting basic power issues before applying what may amount to band-aids is not only more effective overall, but pretty cost-effective. I had an intermittent noise in my system and after replacing every tube, a bad XLR connector and and a bad tube socket, the noise wound up being caused by some dust on the contact plate for one of the battery panels in the line stage. But, having gone through a ground up electrical system "audit" and upgrade when I first moved here, the "noise issue" was independent of all of that. I guess that is to say we are dealing with "systems" and there are many parts to same. Basically, I agree with you in terms of where to start. Where you end up may be a different matter depending on the problem.
As to finding contractors, oy. My favorite was sent to prison in NY but that’s a whole other story....
