I've already tried cleaning all the tube sockets, along with all the 1/4" input/outputs. Tried different power tubes, and swapped around the preamps tubes to see if there was a noisy tube in V1. Happens with a guitar cord in the amp, or when it's not so I don't think it's anything external. I've also tried it on different outlets in the house. No change. Don't really notice it right after the amp is fired up, but then shows up a little bit later. Maybe within a minute or two. Can't hear it when playing, only at idle.
