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!

First- did you ever try shorting the inputs to the amps to see if this made any difference?I might have missed this?
Second - a trick that I picked up from a broadcast engineer friend of mine is occasionally helpful in tracing down this kind of problem - simply plug in a long heavy duty extension cord still rolled up or "hanked" as it came in the package.This basically is a inductor - if the problem goes away - you know the power line is the source - this can also be used to isolate the source of the problem -you keep plugging it in between the wall and different appliances until the noise attenuates - bingo - that's the problem unit. In your case this isn't necessary since you've identified the noise source as the furnace - but if you try this on the amps - that may tell you that the noise is riding in on the power line (probable).

Not sure if this will totally resolve the issue but I am hoping so. A few days ago I noticed I have no neutral coming in from my meter, it seems to come from the power line to my house but the actual metal pipe that connects my panel to the meter only has 2 power cables and it looks as if there is no room for a neutral in there. The electrician I had take a look said the houseprob never had one?! I'm actually away til early next week so when I return I will get the electrician back over and try to come up with a solution.

No neutral, highly unlikely....
Go outside your house to where the power company's overhead power line attaches to the house. Look up at their cable. You should see 3 wires. 2 insulated conductors and 1 bare conductor. That is if you have a 120/240V service... The bare conductor is the neutral conductor. See if the 3 power company's wires connect to 3 wires coming out of the weather head of your homes electrical service.

How about some pictures.....

Well yeah, I actually have a neutral coming to my house, there seems to be some sort of sub panel in the rear of my house maybe that is where the neutral is. However it does not seem there is a neutral in my main panel.
I will get pics up soon, unfortunately my camera is down, hopefully my camera can do it justice.
