Humm from phono but not dc or aux ?

Crank it up on phono (no contact) and move the cables around.

If that affects it balanced would be quieter

Cindyment, have to turn it up to 12 o'clock hear faint Radio station actually too low 

to even make out what they are saying.

But that's way louder that I would ever listen to just past 9 o'clock is abut the limit.

I assume it goes away if the cable from the turntable is removed?

See my post above w.r.t. RF. You may be able to fix it by improving the wire in the turntable / arm, assuming  your other phono cables are properly shielding. If not, may be an issue with phono stage.

At last! This level of noise is not uncommon. It is way below normal groove noise of even a very quiet record. If you have to do this to hear it when no music is playing then no way you are hearing it during music. You can knock yourself out trying to eliminate what is already effectively functionally inaudible noise if you want. Already told you how to go about that.

Only thing left to add, this is exactly why I always tell people my #1 requirement in a tone arm is integral phono leads. Every connection is an opportunity for signal degradation and noise like this. Sometimes even slightly wiggling or moving a phono lead will completely eliminate it- or make it magnitudes worse.

Live and learn.
