A few years ago, my house was hit by lightning. Everything was fixed or replaced. Now when its 90 outside I get a loud buzz in the stereo. I have seperate lines running to 2 out of 3 amps everything is run through a power conditioner which shows volts. When it gets hot outside (cool inside) my voltage goes down to 100 or so and it starts buzzing.
I really don't think this is a stereo issue or it would be there all year, not just when its 90 outside. We found 1 bad wire in our septic system but replacing it did not cure problem.
Only things outside are central air unit, sat.dish, and septic
when its about 100 or more outside, the buzz is constant 90's its intermitant
any ideas on where to start???

this time of year places the power company under higher demands and voltage would naturaly drop in higher temps. you can get a filter for your power or just on that circuit. may help a little

If the voltage drops, then there is an overload on the supply.
It could be that the voltage drops for the whole neighborhood because everyone s running AC. Measure voltage at your panel.
If this is not the case, then the supply cable from the panel to your amps is not heavy enough for the load. Heavy amps should be hooked up to an 20 Amp circuit with 12 ga wire.
Don't know what you are using as a power conditioner, but make sure it is rated for enough amps to handle the equipment. To make sure, bypass the onditioner to see is it causes the buzz.
As the voltage drops as in scenario 1 the condtioner has to work harder...

Electrical problems of this type are always tricky to solve. It sounds as though you are getting magnetic interference. turn off the a/c unit and check if the noise changes. if not shut off the dish and see what changes. since the lightning strike have you added any major electrical appliances? check those. Anything of a magnetic nature in close proximity to the stereo? are your speakers too close? <6 feet? that can also cause hum. good luck. If this doesn't work let me know, I have other ideas.

If the incoming voltage is dropping to 100 that is your problem. Call the power company and let them know, it is probably a faulty transformer.

could just be your area. bad connection to the radio. and maybe when it is hotter you subconciously turn the volume up higher making the buzz more noticable. plus the heat may be effecting the vibrations of the speacker. it is all about air expansion and compression.
