OT followup:
Oberhausen, Rheinland, Germany; power line frequency right now is at 49
Hz, measured with a low cost energy consumption costs meter. Those low
cost meters shouldn't be able to do correct measurements ;). The best
test at home might be to compare the sound of a transformer with a 50 Hz
sine wave.
The times I have measured the power line
frequency to check it's effect or otherwise, I have not measured it as exactly 50.0hz
(when I lived in the UK).
