There was no other issue before I caused the hum, other than things not related to that..
I unplugged one at a time 6EH7 one and two, and then 6EJ7 that are located near the Audio Transformer still a hum in between..
Unplugged the 6M11, still a hum.. Then I unplugged the audio output tube, again and no hum.. I tested that audio output 6AL11 tube just now again, and the short light comes on, on my tester.. Hmmm... Not sure if a shorted tube would cause that, and it be all of a sudden...
