So if you unplug the PSU, for the TT, from the AC power outlet the hum goes away?
fixing hum on Rega Rp6
Hi all-
LIke some other Rega owners, I experience a moderate hum that seems to have something to do with lack of grounding from the power supply. I went ahead and ordered an upgraded power supply from Swagman Labs, which should take care of the hum and have other sonic benefits.

It will be a few weeks before that arrives. In the immediate, I found this fix for running a ground wire from the existing Rega PSU TT.

I haven't done this yet, but my dad (an engineer!) is very excited to try this experiment over Christmas. So my question is once I have the Swagman unit do I need to unhook this grounding wire, or is it likely to add value even with the Swagman?
Finally, will an upgraded power cord with the Swagman also be a worthwhile investment?
Thanks and happy holidays!

Check out this video. LOL, the guy is a little funny to watch. https://www.youtube.com/watch?v=CAY2rRsqHLE The PSU is not a wall wart one though. As for the wall wart. If the plug in blades are not polarized try plugging it in 180 degrees from the way you have it plugged in now. See if that helps. Here is an Agon thread I ran across. This is where I found the above video. Ground Hum with Rega RP6, Exact and TT PSU. https://forum.audiogon.com/discussions/ground-hum-with-rega-rp6-exact-and-tt-psu |
Run a wire from the turntable ground to the preamp ground to eliminate hum! ALL phono systems require THIS! Do this first before wasting money on another plug-in power supply! I am sure that what Rega provides is fine - they have been in business for decades! Also, don't waste money on power cords! Contrary to marketing hype they offer ZERO benefit! Wire is the BIGGEST B.S. factor in Audio! |
