Today, I tried using cheater plugs, but it didn't help.
I've been plugging and unplugging, isolating, trying
different combos, etc. etc. Unless the cheater plugs
need time to work, need to burn in or something, I can say that cheater plugs are not the answer. I do not have dimmers on this circuit. I have tried disconnecting
the TV cable. Didn't help. I don't know if I have mechanical hum, or not. It seems like a weird coincidence that I have 5 items in my system that
use transformers and four of them hum. I have florescent lights on a completely different circuit and when they are on, the humming is much louder. But when I turn off all the lights in the house, I still hear
a light humming coming from my components.
To add another wrinkle, one of my Levinson 436's
hums, but the other is stone silent. I have heard that
a ground loop hum can be identified by whether or
not you can you can hear it in the speakers. I can
hear it in one speaker, but not the other.
I suspect the electrical system, but I don't know
enough about it to know if I am on the right track,
or not. I was hoping the AC conditioner would solve
all AC problems, but it seems susceptible to whatever
is affecting the other components. Or, coincidence or not, I have four components that just happen to have
mechanical hum.
Does this information help?
Anyone?
