London Decca

Does the Jubilee have 4 wires? Try removing one of the grounds.

You could also try grounding the phono
ground wire to the ground of the phono rca
plug/recepticle.

The grounding ideas are worth a try, but Deccas, including mine, seem to have an affinity for hum that defies attempts to remove it.

Thank you so much, Noromance……great ideas. But sadly, no change. I will try to borrow phono stage and see if that changes things. And I have a friend who is a super setup guru too. Maybe he will have some ideas.

JaFox, are you using balanced inputs from phono to Aria? How about running phono ground to mains ground directly?
