Re: (ET) charger problem
The ET isn't Snow White and ferroresonant chargers aren't the seven
dwarves.
They don't whistle while they work; instead they hum. Actually, I'd
characterize it as an obnoxious buzz, not a hum.
You can sometimes mitigate this by physically isolating the transformer
from
the charger case with some kind of resilient mounting scheme.
