Hey Decware crew. I've had my Zen Triode for a bit less than a year, and i absolutely adore this thing! However ... A couple of months back, it developed a scratchy noise after turn on, during the warm up, and only in the right channel. I wouldn't worry too much, but sometimes i hear it during normal operation now.
1) How can i best diagnose this problem?
2) If it's something known/obvious, how can i fix it?
3) If the amp needs to be repaired, what are the steps?
short video (little more than a minute) demonstrating the noise during startup here:

This noise happens with both inputs, same volume regardless of volume pot position. I have swapped speaker connections around and the noise follows the right channel of the amp (doesn't stick to the right speaker).
