HELP I think I have an electrical issue??


A few months ago I had 2 20amp dedicated lines with hospital grade duplex's installed. All was well with my Bel Canto Ref1000 mono's. Well a few days ago I just got a pair of Genesis m60 tube amps. I was noticing a clicking noise coming through my speakers. I first noticed this when I was just warming up the amps with no source on. Then I also noticed the clicking when a source was on with music playing.

So it turns out that the clicking noise is my electric ignition of my gas furnace, is somehow playing through my speakers (Or maybe its just one of them, not exactly sure yet) This is a very strange and annoying. If anyone has any ideas please let me know!

Your best bet, do all the above! I've done everything but the balanced cable (too much SE equipment I love), clean AC is quite an advance in sonics.

Also, if not previously mentioned, make sure you have a good solid house ground.
If you put the previous amps back in place and the problem is gone I would blame the Genesis amps. Like I said, not necessarily that they are malfunctioning, but that they just don't filter out issues with your AC. Maybe they are just more susceptible to noise on the AC line.
I have had amps that showed quirks where others did not.
BTW, what did you do with the Ref1000s?
Hevac1,
Hospital grade receptacles do not have to be isolated ground type receptacles.

I think you have an airborne RFI issue as mentioned by a couple of other people. The tube amp may be more susceptible to RFI than the Bel Canto due to the open chassis design of most tube amps.
Well, due to the fact that I was not wiring the isolated ground correctly I switched out my outlets to a standard 20amp outlet and the clicking is still there, but at least it is connected correctly.

As far as the Ref1000s I sold them along with the balanced ICs that went with them to fund the purchase of the Genesis and my new ICs which have not gotten here yet.

As far as my house ground, I just had that installed a few months ago also, he drove a stake in the ground and also grounded to my water main.

So, now I am at a crossroads, the clicking is not all that bad, can this power do harm? Is it possible that this power that is causing this clicking thru my speakers is also causing a degradation in my overall sound quality (even when the furnace is not starting up?) I say this because it is possibly something I can live with for a bit.

On the other hand, I have contacted my electrician who has not gotten back to me yet, but what would I want him to do?

Run a subpanel with just my audio equipment on it with its own dedicated ground??? Would this have to be another stake drove into the ground??

Also I just unplugged my ICs, so all that was hooked up was speaker wire and power to the Genesis amps and the clicking was still there so even though the ICs were a long shot they are no also ruled out.

I really want to thank everyone for their input, it is very nice of you all.

Best Regards,
Tim
