HELP I think I have an electrical issue??

Well I talked with one of thier service tech an he said this happened to a friend of his that has a home theater also.
He said his friends unit was on the same feed as the power for the home theater so they changed that around so it was not. Then he (this may be an electrical code issue in your area)install at ground rod at the unit and ground it to that instead of the ground to the box. That took care of it. Call an electicain in you area and ask him to make sure your furnace and your sound system is on differant 110 feeds from the 208/230 coming in your house. You could also ask him if he can install a grounding rod. He will know if it is allowed in your area. Ruud factory service around here is Granite Group tel.# 978-458-3200 they were very helpful. They should be able to give you your local reps number. They were not easy to find. No wonder I don't see thier units very often around here.
Tell them mikie sent you. LOL

Other than seeing your system. this is all I can do.
If you have the means I will be happy to come to your location unless you live in the Boston MA. area then I'm around the corner.

Hevac1,

Thanks for digging into this for me, I am going to start with calling my electrician and make sure the furnace and dedicated circuits are on separate feeds. Hopefully that will take care of it.

Also thank you very much for your offer, unfortunately that is a bit out of my means but very nice none the less.
Thanks

So at the suggestion of my local hifi shop they said I should audition a Shunyata Hydra 2.
This did not fix my problem.
Worth a try though as this was something I could try for free.

Any solution yet?

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).
