Low level Hum in Phono Signal Path

There is a distinct low level hum noise evident through my speakers when the phono mode is on. Can't be heard from the seating area but can be heard when your ear is in front of the speaker, either side. This noise is also dependent on the volume; the higher the volume the louder the noise. What is causing this noise and can it be remedied. (Equipment involved: BAT PK 5 phono preamp, Transrotor turntable with Benz Micro Ruby 3H cartridge)

Frepec,
How far away is Your Preamp from the Turntable?

My Rig has a Hum issue... In My
case the phono stage is a
seperate tubed unit,
& the power supply is remote (3+ feet away from the cartridge). However the Tubes are right below the T.T.
cartridge gounded at the Phonostage.
So maybe It is the Tubes causing the Hum?
