The hum is from the speakers. Loud enough to be heard at the listening chair between songs. At night when the power gets worse, loud enough you hear the stereo when muted and the tv is on. Or just in quiet passages in songs.
Please dont start with ground loops in my system. I have tested this with all my stereo gear, accept for the amps turned off, unplugged and the amp inputs shorted. I am focusing my attention on the amps themselves. They need to be not heard at the listening chair when installed as such.
is it still humming when all inputs are disconnected? If not, then it is probably a ground loop and you can try to attach a wire from the chassis of the amp to the preamp and/or source.

You can laugh but this worked for me when I had a hum on my analog setup. Connecting a wire from the phonostage to the preamp took care of it. There is sometimes a small non-zero voltage between gear when the grounds are not optimal.Hahaaaaa. Funny. Sometimes we all need a little humor.

That’s interesting. At night the power gets cleaner, and the stereo sounds better, for me.
