Ground Hum with Rega RP6, Exact and TT PSU.


Greetings.

Just purchased a Rega RP6, Exact, TTPSU and I am getting a HELL of a hum. I am using an Aragon 47K Phone pre amp. I unplugged the wall wart and the cable which goes from the table and it is still there. I seems to get worse when I turn it on and the tonearm gets close to the center of the arm spindle and it picks up a lot of motor noise. Just sold a 28 year old Linn Axis with a Signet Cartridge and never had this issue with just the normal hiss associated as you turn up the volume. It's not noticeable a lower volumes but it is there during quiet passages and it is extremely annoying. The table sounds way better but the noise is very intrusive and honestly I am disappointed after dropping almost $2000. Thanks in advance

I have used ground lifting in the past as well, to help identify ground loops.

Rega's design concepts baffle me.

No grounding

No VTA adjustment

No Azimuth adjustment

etc.. etc......

Can anyone shine any light on their reasoning behind any of this?

@ les-creative-edge

The True/Square design is fine and dandy if the stylus is perfectly aligned within the cartridge body, but good luck with that. This is why azimuth adjustment is vital to me. I can put on a test record and plug in my Fozgometer and quickly adjust azimuth to equally balance both channels in a minute or two. Now I do have a slight advantage, as my arm is a Reed 3P so I can adjust on the fly. If I was using another arm, it would be a more time consuming affair, but non the less, I would be able to get near perfect accuracy (if there really is such a thing) I too am a bit on the anal side! LOL

As for the VTA adjust, I must respectfully disagree. I can hear a difference on different thicknesses of vinyl, and  insist on being able to compensate for this with VTA on the fly. I don't want to be inserting or removing shims for different albums.

Bye the way, good work with your DIY dust cover fix. I do not use a dust cover myself, but I did get a plexi-glass cover for my platter, and it extends over toward my tone arm,bends up, and then bends over to cover my tonearm (hope you can picture that) Obviously this goes on when the turntable is not being used. Well, guess what? When I put the Reed on my TT the VTA dlal on top of the column was too high!!  had to drill a 1 inch hole in the plexi-glass so it could slip over the knob.

Gotta love this hobby!!
