I have just upgraded my audio system. I'm old enough to have lots of old LP's which I raid for background music. My Turntable hooked into my new digital tuner amp has a loud mains 50 cycle hum.
I remember advice to provide a common earth between the turntable and amp to suppress this. My problem is that the Turntable mains lead is only 2 core (no earth wire). Any suggestions as to where on turntable chassis or pick up arm I connect to provide a common earth and hopefully get rid of the hum. It was virtually inaudible through the old (20 yrs tuner amp).
Thanks Jim j
