like  I was saying Nick, I have no access to one.  I am my own tech.  what I don’t know I have to learn.  I’m in rural oregon and *I* was the most knowledgeable person at our local music store (LOL no brag just the truth).

what is a tech going to be looking for in my rig?  if you could point me towards what I need to know then I’d really be grateful, otherwise I have to start with what I DO know 🙁  and that’s to start with good clean power.  I already know my cabling isn’t at fault, power strips are good (I tested those too), I’ve tried separating polarized plugs…. and I also have an isolated power supply for my board (even tho I’m using the stock adapter for my H9).  what am I missing?
