humming in my system

thanks to all of you!!

I use the humbuster to great effect.

Probably the toughest thing to figure out and solve is hum. I had a hum, and it turned out to be a bad interaction between two pieces of gear. I swapped gear, and the hum went away completely. Go figure.

Another thing to try after going through all the procedures above is to get some wire and try grounding the chassis together in various arrangements and also to a known ground such as a screw on an AC outlet. Oftentimes your components can be at different ground potentials and you are hearing the residual 60Hz hum as well as RF and EMI traveling in ground loops. If you get everything grounded to the lowest potential you may eliminate the hum. I have done this many times myself. I would use a 3 prong to 2 prong cheater plug as a last resort, as you can sometimes incur a dangerous shock situation. This happened to a friend of mine and it scared the bejabbers out of him.

pretty much every thing else is plugged in to the Hydra.
