| To Aesthetix users Another update... haven't been able to get in touch with Jim for a second consultation, but now I'm fully convinced it's the front end tubes that are contributing to at least part of the choo-choo sound and buzz.In the meantime, I've taken the gai... | |

| To Aesthetix users First tube-switching results:I just switched the front pairs of 12AX7s - V1L and V2L into V1R and V2R.The chuff-chuff cyclical sound and the 800 Hz buzz have now switched to the right channel. Still audible from the left, but much louder from the ... | |
| To Aesthetix users Here's the latest:The chuff-chuff-chuff (like a steam engine) is growing louder - much louder - and is now more audible in the left speaker than the right. There is a buzzy 800 Hz-ish tone as well. The radio station has vanished since I moved the ... | |

| To Aesthetix users Btw... I took this opportunity to add pictures of each of my components to my system profile, in case anyone wants to check out all this stuff we've been discussing... click the system link below.BestPatrick | |
| To Aesthetix users Strange and surprising resultsSo I tried some of changes mentioned in my last post - with surprising results. The most important change in my mind was plugging the Aesthetix PS into the ExactPower. This however meant moving around a bunch of equip... | |
| To Aesthetix users So Jim White from Aesthetix got back to me last night with some recommendations:- swap tubes around to locate the "popping" tube (this has gone away for some reason - maybe it was an appliance in the apartment cycling on and off)- plug the Io Sig ... | |
| To Aesthetix users Hi Nkj!I've lowered gain to 72 dB on the Io.... this is fine for both the 103R and the Helikon mono in my system.Paradoxically though, I have to turn the volume higher on the linestage, which means that I can hear more of the chuff-chuff-chuff and... | |
| To Aesthetix users A new clue!I just realized that the RF noise has a soft "chuff-chuff-chuff-chuff-" sound to it, like a steam train but speeded up, as if something were cycling in and out.This is more akin to very soft white noise and occurs at the same time as th... | |
| To Aesthetix users OK further updates... no response from Jim via email, I'm gonna try calling him next week. I love Aesthetix and they have been nothing but incredibly helpful when I've managed to get in touch with them. That said, and I know they are a small bouti... | |
| To Aesthetix users More news... the motor on my Garrard 301 is exposed in its skeletal plinth, and I thought this could be generating the problem. It has its own ground wire, unusually enough (I haven't seen this in other 301s), and I tried grounding it at the Io. N... | |
| To Aesthetix users Hi Cello,It's funny, I was just wondering whether to post another update because it seemed maybe it was just me and Nkj at this point!I got the shielded Belden AC cord for the Io and have exactly the same RF - so that's a no-go. (For those interes... | |
| To Aesthetix users Just ran a wire from the receptacle's ground screw to a new screw and hole I drilled in the conduit box. As before ratshack wire says there is now a ground.I have a shielded supply AC cord on order as per your recommendation.I think I will use an ... | |
| To Aesthetix users Nkj: re opening up the main panel for a peek. I can unscrew the circuit-breaker main panel (it was done recently when I had some air conditioning wired installed) and look at the back of the switch which supplies power to the stereo. Is there any ... |
