[AMPS] 8877 Rejuvination

[dan hearn]

Recent postings here have described a procedure for degassing glass
envelope tantalum plate tubes which have been unused for a lengthy
period of time. I believe it was stated that the anode must reach red
color for a period of time in order for its coating to do the job. 
  Do external anode tubes have a similar problem of element outgas
during lengthy storage? Do they have a getter on the inner surface of
the anode which can be activated by arranging to raise the anode
temperature? I have several 8877 tubes which have been stored for
several years and would like to put them to use.
