My Rogue 120 magnums hum; I spoke to Mark and he said this is not unusual for tube amps.
You have to be very close, and it has to be very quiet to notice.

My Jolida JD 1000 has a very low level hum. I only hear it when I right on top of it. So, I sit about 8' away and enjoy the music.
Jeff,
That was the stove silly, not your amp!

My dog suffered a momentary laps of sense when I got down on all 4's to listen for any hum. Boy did he suprise me, that big bastard. My wife hasn't cried from laughing in years!

PS: make sure you don't have any flourecent lights on the same circuit as well as dimmer switches.
