Nad3140 hum

You must excuse my ignorance but I thought that with a selector switch for phono 1 and 2 that this should not be an issue. Unfortunately I don’t have shorting plugs and can’t find any online. This hum exists on both phono inputs and is affected by volume control from silent to loud. This is with or without turntable connected to either input

Shorting a phono socket is doable with a short piece of bare wire (assuming access to the socket is easy).
