HELP I think I have an electrical issue??

Cables are not going to fix this issue, picking up RFI from the furnace is the longest of long shots, and they didn't do it with the other amp, should tell you something. Ground potential is somehow different with new amps, I don't know why.

Sns, do you have a battery operated radio? If so set the band to AM and tune in a weak radio station. Go to where your furnace is located and have the wife turn up the stat to call for heat. When the ignitor starts bet you will hear it over the radio. Guess what? The radio shares no power or ground with the furnace whats so ever..... Airborne RFI.
I am not saying Tmesselt's problem is caused by airborne RFI, but it is a possibility.

We know one thing for sure at this point.
With the old amps and old ics there was not any problem.
A little hard to blame it on the dedicated branch circuit wiring at this time.

For a test I would like Tmesselt to try the ground cheaters on the amps. If that stops the clicking sound of the ignitor then the problem can be solved at the furnace.

Oh, and I have also put the cheater plug on both amps and the clicking is still there.

Why does that not surprise me......

Jea, I can only go by my experience, exactly the same problem, dedicated ground fixed it and a nice sonic boost to match.

I'm also not saying it can't be RFI, just a long, long shot. He didn't have the problem with the other amps and same cable, points to amps as problem. It could be the other amps did a better job of filtering out EMI and RFI.

I just think dedicated grounds are the resolution to all these sorts of problems, I'm not alone, many are using dedicated grounds.

I can also understand why lifting the grounds on amps has no effect. I surmise the garbage is riding on grounds through rest of system. Was always there, other amps may have had better filtering or ground potential has changed. Again, lifting the grounds temporarily at AC outlets will tell if grounds are the issue. Everything is just speculation until this probability is eliminated.
