Help My AC line voltage is 128V

I have recently tested the line voltage reading out from my AC lines. They read 128V ! Knowing that 128V is almost 10% more than the standard 117V and most components inside the equipments have a 5% tolerance only. Would this unusual high voltage damage my equipments? Even though I have all my stuffs hooked onto a delicated line but when my wife uses the washing machine, the power reading jump slight up and down... This is a power spike at a high 128V... Sounds dangerous to me... I now have a habit of unplugging them everytime I finished and I am getting frustrated at this. Will getting a voltage stabilizer help? PS Audio P600 or the Monster Cable stuff?

Yeah, what GS said. I had the same situation and the power company retapped the transformer on the pole outside my house to bring it down.

Oh so 128V is pretty usual thing in some area because at least Herman had the comapny turned it down for him. My light bulbs in my house keep blowing and this is getting ridicurous! I spend almost $10.00 on light bulbs every 3-5 months! At least 1 light bulb blows in every 2-4 weeks! I suspect the spike kills them all the time. I will try to contact ConEd to either "show me" that it's is okay or tapped down the trans. like what they did to Hermans' neighborhood.

Waiting for more inputs before calling ConEd on Wednesday. Who else has a measuring of 128V? Would a regenerator like PS Audio P600 or Monster Cable Voltage Stabilizer do some help? I have two 20 amp delicated lines and I want the purest possible so I don't want to add anything unless I have to... If the power from the delicated lines are clean enough I prefer not to add any stablizer / regenerator...

The choices are:
-----------------
CHOICE A
If the delicated line's power is clean enough, I prefer not to get a regenerator / stabillizer and will call ConEd to fix the problem.

CHOICE B
If the power fromt he delicated lines are not clean (let's say at least 90% clean?) I will then get a PS Audio P600, Monster Cable Volytage Stabilizer or an Exact Power EP-15... which steps down the voltage to 120V and cleans the power at the same time... If so, which unit above is the best? or do you have anything else to suggest?

ALL YOUR INPUTS ARE GREATLY APPRECIATED!
I WILL SHARE ALL RESULT LATER ON IN THIS FORUM FOR WHICHEVER WAY I GO WITH! THANKS!

I blew a few tubes on my Manley gear. Their engineers suggested voltage stabilization. I am using a Monster av2000 and a Hydra 8 for conditioning. I haven't had a problem yet and the sound is improved.

Extremely happy with my PS Audio regenerators. Have the PS600 for my integrated, PS500 for the digital front end.
Holds the voltage rock solid.
Best,
