Do all tubes glow


In my CDP the two 6922 tubes glow and the two E83CCS do not glow but are hot, and the unit seems to play fine. Thoughts?

In my CDP the 6922's glow brightly but 12AX7's emit very little light. Hey, do we have the same CDP?
jl35,
What tubes are you using?
Currently I've got a pair of old Mullard 12AX7 and a pair of Telefunken 6922. Figured I'd let the English and Germans fight it out one more time in my CDP.
jl35,
Yes mine has volume control. As far as I know the tubes would only be breaking in while on not when the unit is in standby.
I think they’re breaking in any time juice is flowing through them. So if they’re glowing even with no music they’re breaking in.
Caveat: I'm no expert on this. If I'm wrong I hope someone corrects me.
