Phono hum

Help! I have a VPI Scout with Dynavector 10x5, Bellari VP129 phono preamp, Anthem TLP1 preamp/tuner and Anthem MCA2 power amp. I have a hum problem I can't get rid of that I didn't have with my Music Hall MMF-5Se turntable. I tried the VPI interconnects (with the integrated ground wire running from the turntable ground to the VP129 ground terminal) and that lessened the hum but it's still there. I also have a loud pop when powering off the Scout motor. The TLP1 has no phono section so I am using the sat/aux input for the turntable. I've run a ground wire from the center screw on the AC outlet to the chassis ground screw on the preamp and that made little if any difference. Any suggestions?

Radrog,
Did you disconnect the ground wire that's built into the VPI interconnect cable, the ground wire that goes from the turntables ground terminal to the phono preamp ground terminal? Or did you disconnect the ground wire that comes from the underside of the tone arm to the ground terminal, the one that was pre installed on the turntable?

Stringreen, Are you saying that if I just zap it with my Zerostat that will remove the hum???

I grounded everything including from the TT to the preamp itself...no help. I bought a Cambridge 640p and magically the hum and loud pop have disappeared. I think the VPI's motor is a little too "magnetic" for the Bellari.
