I don't have full vertical either, Im missing the bottom inch or so, the vertical output tube gets very hot I can't even touch it during operation.

A new 6BK4 is perfectly clear. If that tube is that dark, it's pretty well spent. New 6BK4's are very reasonable at ESRC in Florida. They show a 6EL4 for $40.00 USD. Why, I don't know. ???.... Is the vertical output a 6HE5? It's a fairly hot running tube. Probably a lot of faults in that set that have to be sorted out, one at a time.
