Years ago I had the same issue. I put the meter in the wall outlet and it fluctuated more than is acceptable. I live in a rural area and at the end of a line. My more than satisfactory fix has been a Transcedent Power Conditioner. It is sold on line by Bruce. The conditioner can be bought as a completed unit or as a kit. My summer time blues are now only as music. Hope this helps. Steve Levick
Summer Power Woes
For the past month, I've found my system to be a little stale and uninvolving. The other week, it became apparent that the sound was significantly better in the early morning compared to the evening. This morning, we finally get a 'relatively' cool morning, and the sparkle is back.
Just a reminder to not judge or make critical comparisons during the summer when the temperature is over 100 and everyone's AC is going 24/7. Systems can be very dependent upon the quality of electricity, even when one takes many steps to minimize this effect. I am convinced the effect is quite clear under these extreme conditions. And, it is not just your own ACs on the power line, but everyone else's.
