This is all in my house. I've relocated a couple of times in the last five years. I've really struggled to keep recording, but i do play music with friends. I want the stuff to still work. After we moved into our current spot, some friends installed an ac unit at a cut rate and I'm grateful for it. Idk, but i suspect that it may draw more power than the old one and may strain our electrical system. It is close to my set up. That's why I tried running extension cords around the house. I was trying to see if another circuit might not have the problem. I can record for hours without issue, but at any time, it might go bad.
