High pitch pulse sound coming from stereo receiver

I am getting a high pitch sound coming out of stereo in a pulse that would make a dog loopy. I do not have a sophisticated setup. The stereo is plugged into the wall. Apple TV is plugged into wall and TV. Router plugged into power strip along with DVD player. I switched out all RCA plugs and speaker wire.

No buttons like tape monitor or special sound effects are on and everything is plugged in normally. The receiver makes this pulsing sound when plugged in but is turned off. 2 feet away I have a Mac computer but it is not connected physically to anything but streams to Apple TV when it is on (which isn't often).
I suspect my stereo receiver just might be going bad as it is an early 2000s model. I bought it used 5 years ago but don't recollect hearing the noise then. I never play music loud so that isn't an issue.
Any thoughts on this would be appreciated but not urgent.
