re: A-710 high noise floor

I have this on my bench for a complaint of high noise floor.
The power supply rails are clean, the volume control is noisy all the way through it's travel but the noise does not increase in volume with full rotation, the mute button seems particularly contributory to this noise when actuated. Acts much like a lifted ground. All the inputs sound good, aside from the high noise floor it still sounds quite good. I doubt the output transistors are bad.
