Phono stage hum at midpoint on volume control.

Have you checked and confirmed that the tonearm ground cable is connected to the phono stage ground screw/terminal?

@nonoise asked a good question as well.

Sorry, but I haven't commented on this thread. Maybe someone with a similar sounding name like noromance? 

@nonoise my bad hahahaha…it was @noromance who commented and you became a victim of auto-fill when I was trying to tag him. 

@audphile1 I'm with you on the auto-fill, which ranks right down there with spellcheck. 👍

Happy to be in the same room as @nonoise
