Help on Electronic Problem
When it is about to have the fan go on, the static starts... often the static stops once the fan is on (though, not always).Sounds like the fan is controlled by a thermostat. Automatically turns on and off?I still think it is a faulty wiring issue... 
Help on Electronic Problem
I would guess the fan motor is a Shaded Pole type motor. As a rule this type of motor would not cause the problem the OP is experiencing.At this point the OP needs to contribute more information......

Gas log fireplace?Full time pilot light? Or an electronic ignitor that lights the pilot? Are you sure the static is not being caused by an electronic ignitor? Can you light the fireplace and leave off the fan? If so try that first. No static, then... 
20 amp power cords vs 15 amp power cords
Sorry to complain but those posts above have all sorts of theory, and no practical advice for buying a damn power cord for your amp.03-19-12: ElizabethTheory? I gave the facts mam.... Just the facts....Speaking of facts an after market power cord ... 
20 amp power cords vs 15 amp power cords
As far as the ampacity difference between a 15 amp plug an a 20 amp plug there is no difference. Blade size and thickness are the same. Blade configuration is different.... A 15 amp plug will fit into a 15 amp or 20 amp receptacle.A 20 amp plug wi... 
AC Line Conditioners
Disconnected the cable feed (from wall to power strip )and low hum still present in amp and CD player(sleep mode).Wrong cable.....Not the AC power cable..... Disconnect the RG6 coax signal cable, (that comes in from the CATV provider), from the At... 
'New' power amp introduces ground loop hum - help?
You have a difference of potential, voltage, between the CATV company's coax cable and the grounding system of your home.Get one of these.....http://www.cs1.net/products/jensen_transformers/VRD-1FF.htm. 
AC Line Conditioners
These include a Plasma TV and At&T receiver,Good chance you are experiencing a ground loop hum caused by the cable feed to the At&t receiver. Disconnect the At&t cable from the receiver and take a listen for the hum.Jensen makes a good... 
cable burning
Al,Heat = power.....Wonder how much amp output power the thing consumes?Jim 
Resistor to tone down tweeter?
Mcpherson,Agree with the other posts.Just to add.....Make sure you have the speakers set up properly.You might try tilting the front of the speakers back slightly. That will raise the tweeters dispersion angle slightly above your ear level when si... 
Balanced vs standard power
Are you saying that by adding 220uf to the circuit I have effectively lowered my 10kVA xfmr rating to 5kVA?03-11-12: NormNorm,I agree with Al's explanation. Not sure why the manufacture shows 41 amps FLA for each winding instead of 41.67A.... 5000... 
Balanced vs standard power
Al,Just wonder if the poor PF, caused by too much capacitance on the AC line, is doing anything to the power xfmrs and switching power supplies of his audio equipment.You are the EE here.... What say you?Jim 
Balanced vs standard power
Good points, but in no. 2 shouldn't "lead" be "lag"?03-10-12: AlmargAl, You are correct.... Should read Too much capacitance causes the voltage to "lag" the current causing a leading power factor. Result is a low power factor.... Re the 220uf, tha... 
Balanced vs standard power
By adding a 220uf capacitor to the secondary side of the transformer,03-10-12: NormNorm,A word of caution when adding capacitance in an AC circuit. Two things that can happen.(1) The capacitor can raise the output voltage.(2) Too much capacitance ... 
Belt noise on my AR turntable
Took a close look at the motor pulley as well as the sub platter and sure enough there was a black grit residue on both where the belt traveled.I cleaned both with alcohol and wiped dry.Couldn't believe the amount of black junk that came off.I the...
