Don’t coil power cables or any cable for that matter. Looping is best but isn’t particularly practical, figure-of-eight them if you need to take up any excess.

I found similar issues with valve amps: vibration of components and inductive coupling between different transformers in a few cases.

I'm curious to see if the power conditioner will actually eliminate the noise, it is essentially running off the same circuit as the PSU1. Ideally, I would prefer to run it off the power conditioner if it does in fact eliminate the noise but this would go against the advice from the manufacturer to always leave the PSU1 powered on. I will do some troubleshooting soon.

Funny you mention that, all power cables are actually figure-of-eight'd. Most people assume coiled is figure-of-eight'd when it comes to power cable, although I don't generally do the same with signal cable unless it's something like Neutrik NL 2/4/8 cable.

Thanks for your reply Ian, I will do some troubleshooting this week and let you know if powering the PSU1 from the power conditioner does clean up the noise. The issue with this though if successful, is that the PSU1 will no longer be powered on continuously which goes against the manufacturers recommendations. My argument is that I have surely passed the burn-in phase, as I have owned and used the product for almost two years now. Also worth noting, there is a RJ11 outlet located directly behind the turntable, roughly 1/2 a metre, and RJ11 cable running behind my main cabling. The RJ11 is strictly a internet line, but I'm curious now if this could be causing interference?!

Well that's interesting. I may have to dust off the multi-meter and do some troubleshooting! Also, I just mentioned this to another reply that there is an RJ11 outlet and cable for the purposes of internet in this room. It is possible that this may be the culprit.

Hi guys,
Quick update on this post. I was dealing with grounding issues between my newly installed tonearm (Jelco TK850S) and my phono stage (Graham Slee Era Gold V). Unlike the stock tonearm, which is grounded to the turntable chassis, and then grounded again following the RCA interconnects to the phono stage, the Jelco tonearm is only grounded once via a 5-pin DIN-RCA tonearm cable to the phono stage. The solution to this grounding problem was to ground both the tonearm armbase/collar to the turntable chassis, and the turntable chassis to the phono stage. Continuity had passed on various possible sources including tonearm cable to tonearm, tonearm cable itself, and tonearm itself. I'm still scratching my head as to why there was a grounding issue in the first place, but I did think it was odd that the new tonearm was not directly grounded in some way. No other users in the Hi-Fi community have reported grounding issues from Jelco tonearm's, and unfortunately Jelco has ceased to operate recently due to operational issues from COVID-19. Thank you for your assistance on this. |
