Eliminating humming & buzzing


What is the best way to have a clean sound? When I hook
up the grounding connector from my turntable, it reduces
about 95% of the humming/buzzing; but not all of it. The
noise is still there even if I unplug the power from the
table.

Is this simply a grounding problem, or is there something
more that I need to do? The table is hooked up to a
receiver which is not at all grounded; I just connect the
table ground to the ground in my power strip. Kind of
primitive, I realize, which is why I'm asking here.

Thanks!

If your receiver has a two prong power cord and the prongs are both sized the same, it is possible that you have the receiver oriented for the "least correct" AC polarity. If you can, unplug the receiver from the AC, turn the receiver on and let it sit for a minute or two. Then turn the receiver off and plug in the AC with the power cord oriented in the opposite direction. It is possible that this will resolve your humming problem.

There was a thread that i wanted to reference in the Agon archives, but i can't find it after doing a few dozen searches. If i stumble across this, i'll post it here since this is not an uncommon problem. Sean
