If you remove the heads, then you have to align them. Several times in
the field I have unfolded a tex pad, placed it between the heads and
hand launched them. Carefully sliding the pad back and forth cleans
the heads and most of the time removes any oxide. A small tool can be
used for stubborn oxide. I haven't read all of the replies, but is the
pack beyond cleaning? Do you have access to another?

[Tektronix 4012]
I wouldn't give up on this terminal just yet.
Surely not! The problem is simply that I have three babys to care about
at the moment: The RK05, the 11/34a and the 4012. I am more or less
finished with the RK05 for the moment due to the damaged medium. More
when I get a new medium... I still haven't looked at the 11/34a. Will do
some PSU testing tomorow before I power up the logic. If the 11/34a is
well and alive I'll return to the 4012. It would be really nice to get
it back to live. Maybe I'll replace the tube of the 4012 with the tube
of the 4006. They look the same, but the 4006 tube isn't damaged.
Would it be a sacrilege to use a HP scope to repair a Tektronix
terminal. (I have only HP scops.) ;-)
