RE: Tube amplifier hum

two things to try. First move your head amp off the other amp. If the hum persists try running a ground wire from a case screw to the ground connection on your amp. By this you can at least tell if you have an internal grounding problem. If the head came with a two prong cord it should be double insulated, which in audio gear is unusual.
