Jamie,
You can replace the audiophool gold standard tube (6DJ8) with a common 6BK7A. It's a TV tube so very little demand for them. Gain is a little higher and transconductance is a little lower but it works. Most of the scopes I pickup for free or for a few $ after being stripped are usually only missing the audiophool tubes like
6DJ8, 12AT7, and 5AR4, the rest are usually left unless you get a scavenger that wants to make sure he hasn't missed a money tube. BTW a workable replacement for the 5AR4 is a 5V4 again a TV damper tube and very little demand outside of the TV collector community.

Yes, this tube is definitely toast. It is all white inside, so it will have
to be replaced. One that the audio guys love, too: 6DJ8.
