Thanks all. I will be talking with Mike at MS to help me through this as well. Hopefully the following will answer a few questions. It currently resides on its own shelf. Power cords do not traverse interconnects. Noise has a sea shore charaacter, and occurs whether plugged into an AC line conditioner or wall. Swapping tubes is not an option since the unit is being field tested.
How to Manage Rhea "Noise"
I have noticed excessive noise from my Rhea. The balanced out is noisier than the RCA out. Gain greater than 56db makes the noise completely unacceptable/clearly heard from my "sweet seat." This prevents use of ultra low output moving coils. Any suggestions. By the way my old PH-3 was dead quite. Go figure.
