Clean AC power

Thanks for the suggestions. You said you found out that your power was very dirty. Did you actually measure it or just discover it by adding the conditioner?

What measurements did you get, with and without conditioning?

I know that there are a zillion causes of electrical noise within the home. I'd like to know --just out of curiosity--what effect on the mains power the following have:

Step-down transformer feeding my house. It is at the end of the line, no other house being supplied. Does the transformer by nature clean up the power?

All audio equipment on a dedicated circuit and single heavy duty outlet. I suspect that the outlet is only better than a standard one in safety specs.

I cleaned up and reseated the hot wire coming from the breaker in the panel. I also removed a fair amount of grunge on the breaker clip. Don't know if this had any audible effect.

I tried a 1-to-1 transformer to feed all the front-end electronics. It was a fairly cheap unit but rated sufficiently. Can't say I herd any difference.

Any insights on these measures?

4krowme, The grunge I cleaned off wasn’t greasy, or oily like the de-oxit spray. It was the sort of powdery oxidation that’s so common.

Also, I have the same question about a dedicated circuit. What is it actually doing?

jea48: My panel is a Challenger SB40. The buss material is hard to determine; it is clearly not raw copper, but has a shiny metallic finish. The contacts in the breaker are copper.

I cleaned the load wire with a fine metal brush until the copper was shiny, then sprayed Deoxit: same for the the load end. Didn't touch the buss connector.

Thanks for your detailed response to my last question.

jea48: Who would have thought that cleaning a circuit breaker's contacts would be so dangerous? Should I move my family to a hotel until the problem can be fixed?

jea48: Appreciate your followup.
