so I have had some issues lately with static and loud pops coming through the right channel of my Rega Mira 3. I had it serviced by a Rega tech and he couldn't find or reproduce the problem. The store that sold me the amp 4 years ago kept the amp and tried to reproduce it there for a week. Still nothing. I bring it home again and ten minutes later the issue is there again. I must be going crazy or is there a issue I might not have thought of?
