Ground Hum with Rega RP6, Exact and TT PSU.

Have you made sure of all connections especially the ground wire from turntable to preamp...I know its a dumb reply but the sort of issue your having could mean you have a broken ground wire or related problem.

Hi pivetta- In addition to what Stefani brings up, you might want to try one of the following (or both having been through this recently with a new phono pre and turntable).

I too had a bad hum and what solved it for me was to place the phono pre away from all other equipment and also swapped out my "fancy" silver interconnects with some basic shielded RCA cables.

You should try moving the phono pre first and then maybe a cable swap.  I'd be surprised if these changes don't solve the problem for you.  

I understand that rack placement of the gear may not be ideal, but could make a night and day difference.

Try it out and report back.

It sounds like you have too much gain. If your Aragon has any type gain adjustment, make sure its on the lowest setting. You may end up having to get a different phono cart or phono preamp.

If you know someone who will lend you a MM cart, try it. 

Thansk for all the responses. The Rp6 like all Rega turntables does not have a ground cable and after doing some research i have read that this is a common problem with these tables. Sfall mentions to lower the gain which It is already done. I had the table here at home on loan for about 10 days from my local dealer and I did notice that there was some hum but not as bad. Something happened after that period? Don't know. What makes the whole thing worse is that when I turn the tt psu on the noise increases as the tonearm gets closer to the spindle or where the motor resides. I will try moving things around but space and placement in my rack makes it difficult. Best regards to all. 

I have a Rega RP3 with the Exact ,TTPSU, and the Rega Phono Pre Amp and have the same problem. I sometimes get the hum as i place the arm over the album not all the time. But as you move the arm closer to the center of the album the hum increases. I do not hear it when playing a album not even between songs. One thing I did do that helped the hum when just placing the arm over the album is I removed the plastic clamp holding the cable to the turntable freeing up the cable. This fixed the hum occurring when I placed the arm over the album most of the time. I have learned to just live with this as like you this didn't start when I first got the table. If anything works for you please let me know. I had been thinking of trading up to the RP6 bought the RP3 from Sound Stage and they have a nice trade in program but if your having the same problem don't think I'll be doing that.
