I’ve been looking at the graphs for the performance of my P5. The following has been consistent over the last three months (that’s as far back as I looked). Average THD output (red line on the graph) ranges between 6.0 and 7.0 while the incoming THD is consistently around 1.5.
After writing the above, I decided to look back another couple of months. Something seems to have happened on May 25. Prior to then I was cruising along with nice low THD and output voltage just over 120. See the screen shots below. I believe the P5 did restart itself once but I don’t remember the date (not very recently, could have been May). I haven’t changed any equipment since last fall; I have a DS Senior, a DMP, a turntable, and a BHK 250 plugged into the P5, which I don’t think would overstress it.
Do these data indicate a damaged unit, or is it something I can adjust? Should I stop using the P5?
Thanks for any suggestions!
