I wiped off the tubes and snapped some better pics this am. I just cant spot
anything that looks like it got hot and smoked up. My uneducated guess is
that one tube went bad probably 30 years ago and maybe it was
parked in some old lady's house with a fabric over it used as a server or ?
When the guys plugged it up at the S.A., it heated up and was maybe trying
to burn the dust off the tubes and thats what they smelled, I dont know?
Maybe the ? in that enclosed metal box looks a little sootey.
