Usually it is the wiring coming in, one way or another. Often swapping interconnects, or even moving them around can stop it. Using some metal mass near the cables can also block the problem. Anything made of metal, and heavy can do. Some wrenches, a hammerhead, etc.If you still get it with NO cables attached to the preamp, then it may be coming in on the AC cord. Try a different AC cord. Or the same heavy metal bits on the AC cord. (lots of them). Or on the preamp case over the area the phono bits are.
If it stops when you disconnect the phono IC. it may be the cable or the cartridge. Try a different cable there. and the metal bits on top of the cable. Or try moving the TT. The caartridge may be in a bad position for RF in your home. The problem may be you are in a strong signal path of a microwave tower
If none of that works.. You need a different preamp?

With the friendly advice from my fellow inmates and the OEM manufacturer of the Preamp, problem solved.
It was the Satellite Receiver decoder unit. It was putting noise on the power line.
I disconnected everything, and brought the system back one by one and voila, as soon as I connected the Satellite Decoder box, the noises returned.
Who needs Satellite when I have LP's and Reels?
Musica maestro!

Not only did the noise disappear, taking out the Satellite Box has lifted a veil on the system. Amazing how AC contamination affects the other neighbors sharing the same outlet.
