How do you tell how dirty your power is?

You need the Clever Little AC Power Analyzer. It appears to be a set of plain old television rabbit ears but in reality accurately detects the quality of your ac power. Place it near the outlet in question for 12 hours and then very carefully move it outside to the location at which AC power enters your residence. Make sure the wind is blowing at least 20MPH. After 24 hours if the rabbit ears are facing north/south and it is an even numbered date, your power is fine. It they are facing east/west, your power is suspect. On odd numbered dates, the wind must be over 40MPH and the north/south and east/west positions must be reversed.

If the wind speed is such that the rabbit ears move, the use of magic pebbles to anchor them is suggested.

Bill, sounds kind of complicated, is this a service that can be provided by Audiofeil International?

No.

It is far beyond my technical expertise.

However, there is another vendor advertising here far more qualified than me.

In fact he might even be an MD.

Elizabeth, is this tongue in cheek?
