Under your turntable, there should be a ground connection and/or a place you could connect a small ground wire from your tone arm to this connection. Anything metal will do. There should be some screw or something on your tone arm base to connect to (probably underneath the table.)You don't want to connect to anything that would restrict tone arm movement.
I can't say for sure, but sometimes this will quiet things down. The wire to your preamp is chassis ground for the table itself. You also need to be sure this includes the tone arm. Sometimes the tone arm gets isolated and then it will pick up noise such as you describe.
Make absolutely sure your cartridge connectors are correct also.
