Default Hum From Power Transformer Normal?

Just got the SSE fired up a few days ago, it sounds great. Iím getting some hum from the Edcor power transformer, donít hear it at the speakers, just when standing over the amp with no music playing. Hum does not bother me, just wanted to see if this is normal or something I need to be concerned about, donít want to fry the transformer. Thanks in advance for your help.

It is probably normal. If you have the correct fuse (2 Amp for US 120 volt power, 1 Amp for 230 or 240 volts) I wouldn't worry about it. Try tightening the 4 bolts that hold the covers on. They also help keep the laminations tight.
Tubelab, it's 5 year mission. To explore strange new tubes, to seek out new circuits and topologies, to boldly go where no tube has gone before......
