Ground Hum with Rega RP6, Exact and TT PSU.

A big reason I run from Regas now besides the overly cheap build quality the terrible plastic speed control the poorly designed dust covers....They love to hum. My RP6 did I couldn't rectify so off it went to agon. I owned a good bit of rega over the decades but not any more run run from rega products get a VPI dont look back.

I hear you johnk. I think that I have buyer's remorse. I totally agree with that the sub platter is not all that great but once you put the platter on top it has lots of inertia. I think the tonearm is very good. I was talking to my wife and wished that i have never sold my Linn Axis which was DEAD QUIET after 28 years of use. The Rega does sound better in my opinion and I will give it a chance. I am also considering doing the incognito Wiring upgrade to see if that helps. I will talk to the rep and my dealer to see what they say. 

lenmc2964. I will try what you suggest however I have learned in my life that if something works keep it and do small improvements. I listen to a lot of classical music and there are soft passages which you can hear the hum a bit more. I am also disappointed that you have to hold the tonearm lift mechanism otherwise it drops too quickly and it tends to jump into the track and not from the beginning. AARRRRGGGHHHHHH.

I would send it back and purchase another brand turntable.  FWIW, I have had 3 VPI turntables over the past 25 years and I  never got a hum from any of them.  I am using a low output mc cartridge (.3mv) and no hum.

My RP6 has never had a hum and I've used mine with 3-4 different phono preamps as well without issue.  Also the lift mechanism also lowers very slowly.  More than likely you have a defective unit. Since it's on loan try another or send it back. 

I had a similar issue years ago with a P25. Since Rega doesn't use a ground wire on the tonearm, I ended up getting the tonearm retired with the Incognito kit. That ended my issue, however I believe that Rega uses the right channel ground of the SE connection for ground. I did try an alligator clip before investing, that revealed the solution before I invested. So you may try that, as a note I have an RP10 with a Kleos and have no ground hum. 
Good luck
