    I have a hum when playing my turntable. I've attached the turntable ground to the pre-amp (actually a receiver with pre-outs), and then to the separate 2-channel amplifier, and get hum in either case. Do I need to connect the pre-amp and amp grounds together?

    Are your turntable and preamp plugged into the same circuit? This reduced (but did not eliminate) some hum I had in a system.

    Sharing the grounds might help (although all earth grounds in your house should be the same).

    If you have an old turntable, it may not have a polorized plug(one wide prong for the grounded conductor, narrow for the ungrounded conductor). If this is the case, rotate the plug 180 degrees and plug it in. It's important that all the electrons be moving in the same direction.

    Worth a try anyway!
