sorry for the vague description.

the tube gets a reddish glow like the heater or tube is on. this only happens for a brief moment. i can see it on the inside at the base area of the tube. there is nothing that would alert me to a major hazard.

it happens so fast i cannot tell if it is the heater or not. it is more like a brief flicker.

it is no brighter or exciting than what happens when the tubes are heated and playing music. it happened to catch my eye one time.

thanks
brian
