Are you connecting the turntable ground wire to the ground screw on your amplifier, or to earth ground? It needs to go only to the amplifier, any other connection will make hum.

Also, shure cartridges sometimes strap one negative terminal to chassis ground, meaning if it does not hum with the ground wire disconnected leave it disconnected. This isn't a safety ground, it's just for hum reduction
