Hi patwho,

Besides kcarlile's good suggestions, you might try plugging your EP350 into the same electrical circuit as the other components, or, if it's already in the same circuit, try a different electrical circuit than your AV receiver, video display, etc. That's how I got rid of a hum/ground loop with my own EP500.

You'll also find an article of mine on getting rid of hum in the Axiom Article archives.
