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?

Curious rja if the new tubes break in only while playing music, or simply by having the player turned on?
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.
Thanks rja, Do the tubes break in simply by having the player on, or only when music is being played? Thanks...
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.
