House AC Line Variance


A question about AC...

My measured AC line voltage runs from 123 to 130 VAC. Lowest in the evening and highest in the morning. I assume this is due to load in the neighborhood. It really affects the bias on my tube integrated.

So is this a normal range (seems high) and is that big of fluctuation?

Is this something that can be "controlled" at the house or is this the power company?

Thanks for any info.

Benb, the APS will not even approach the sound that you are getting from the Sound Application. I don't have any experience with the Thor, but other voltage regulators are sonically poison. Fortunately, my line voltage varies .2 volts from 124 over an entire week when I had a voltage recorder on the line. This is in a rapidly growing community with much demand from air conditioning. It can be done, but my city power seems more interested that for profit providers. I think your voltage is too high and probably will shorten the life of your components. I would press your provider to deal with your over voltage problem.

Not long ago I visited a friend in Nashville. In the Summer he had a maximum of 114 volts and a low of 103 volts. The sound was awful. He will not raise hell with the TVA to do something. I cannot understand why people don't raise hell if need be to get the ac they have a right to.
G_m_c, yes, I had not thought of changing the taps to get what you want. If I recall, however, the lowest tap is 110 volts. Would going in on that and out on 117 give you a kick up?

Benb, I have had very poor luck with ac filtering. The IsoClean system, the Walker Velocitor, and the Sound Applications are the only units I have heard that help more than they harm. My house was struck by lightening with the system on and plugged into the Sound Application. While many things were blowen out in the house my system was unaffected. I had the computer on a UPS device. It and the computer were gone. That was learning the hard way for me. Incidentally the lightening blew a hole in the gas line going to a water heater and ignited it. A day later when we had no hot water, I checked and found an open flame. Luckily it was far from any wood so our house had not burned down.
