Rega Turn Table Hum

I have a P5 and have recently noticed that once the arm/cartridge is at the last song nearing the lable, EMF hum is being introduced I believe from the motor into the cartridge. I never noticed it prior to instaling a groovetracer subplatter, but according to my local Rega dealer they have experienced it using the standard plastic subplatter supplied with the TT.
I would be very interested in hearing from any fellow Rega owners that may have a corrective action to eliminate the hum.
I recently came across (Direct Music Web) a product called ERS cloth which is suppose to block RFI (Radio Frequency Interference) and EMI (Electro-Magnetic Interference). ERS cloth is a blend of carbon fibers coated with proprietary metals that make it virtually impenetrable to RFI. It comes
in 8"x11" sheets.
If any one has any experience with the ERS cloth I would also be gratefull for your input.

quote Theo: I found that if I took the ground from the right channel connector and grounded it to a seperate ground it helped

Could you explain in a little more detail how you did that?

Grounding the Lehmann may also help. And you might remove and reinstall the oe subplatter if the metal of the gt is amplifying the hum.
Even though the locall dealer has encountered a similar hum using the supplied sub platter, I dont recall having this hum untill after I had replace the sub platter. I should probably reinstall the oem subplatter. Grounding the Lehmann also sounds like a good idea
I would like to thank everone who has contributed.
First chance I get, I will report back the results
Thnx again
I have a new P3 with the TT-PSU and a groovetracer sub-platter.

I was having nasty woofer rumble, not hum, but the problem could be related. It turns out that the TT-PSU was too close to the table. I have the table mounted on a wall mount, with my stereo stand decoupled below it. However, there was a large enough gap between the top of the stereo stand and the bottom of the wall mount to place the TT-PSU. Once I moved the TT-PSU as far away as possible, the rumble went away. You might want to give it a try.
Thnx, I have some flexibility in my rack(s), so I think I will try to sperate the TT,TT PSU, Lehmann, and Lehmann PSU
as far from each other as I can get them. But bear in mind that the hum I am experencing is not noticable untill the stylus gets really close to the lable and stops all together when you move the cartridge about 1/2" away from the lable.
Thanks for your help
