Phono cartridge noises

They appear to be tube phono stages. Try a solid state one like a Schiit Mani 2. You can also try adding a RF filter capacitor across the phono input. Add a ferrite bead to the 'hot' wire coming from the RCA plug inside the amp.

There is no reason to believe that an SS phono stage would be less sensitive to RFI. In fact, an SS stage is more likely to be MORE sensitive to RFI, because an SS stage will likely have a wider bandwidth, not that that extra bandwidth, for example above 100kHz, is necessarily vital for audio.  Also, in this case, the RFI is likely to be airborne from the nearby tower. Thus adding filters across AC and audio inputs is not likely to completely eliminate the problem, although there is no reason not to try it. In the worst case, you may have to consider placing your phono stage inside a Faraday cage type of shield.

The issue occurs when the OP plugs in the phono lead so I cannot see that working.

Do you use or have any LED lighting? I use LED lighting for mood at night but I found that it gave me noticeable static and electronic noise. When I turn the LED lighting off the noise goes away. Just a thought. Only affects the phono stage and none of the other gear hooked up. It is a strange thing and I have not found a way to eliminate besides turning it off. Just one more thing to check and may not have any affect at all. 

Noromance, Airborne RFI can enter via the cables or any piece of equipment, in this case the phono stage. Once it gets in, it can be propagated by cabling anywhere. so why is the observation that phono needs to be plugged in contrary to the airborne hypothesis? Or are you only wondering whether the Faraday cage would help? I assume cables are shielded, although maybe not adequately.
