Electricity fluctuations

I live close to the end of the lines at a rural set-up, I have 100' underground cable coming to my house. I installed a 20amp circuit and an 8 gage 35' dedicated line to my stereo. I get current fluctuations that I could not detect through the voltage indicator of my PS 300. I run various air cleaning filters in the house and I hear them slowing down and accelerating intermitently but what bothers me is that I can't use my turtables' power supply (VPI, SDS) at the recomended lowest voltage of 72 volts because the motor stalls. The power company tells me to check the cable that comes in my house but then when I operate the turntable late at night, after 12pm it runs okay at 72volts. It is mostly during peak hours that it stalls. The SDS is plugued in a PS 300. Can anybody tell me what to do to corect this problem? I am handy but not too technically educated.

Do you have a transformer on the power pole at the end of your 100' line? Or are you using the same transformer as your neighbor? If the latter is the case, you can request your power co to put your own transformer up for you - at their cost. I did this and cured the same problem you are having. In power co. lingo it's called "a too big line drop" and it is technically not allowed. You may have to do some talking and calling to get it though.... The fact that you are ok at night supports this (although power is generally smoother at night anyway).

Do you have a heat pump? If so, check to make sure it is well grounded. Mine would cause line dips when it came on. See if you can time the fluctuations with something like that coming on (water well pump can do it too) so you can isolate the problem. Good luck!
