  You may be getting confused between the steel-shelled tubes which have the glass base and aluminium cased types such as EF50 which had an all-glass type enclosed within a metal shell

    but the old octal style base metal tubes have glass only at the base.

  "Underneath that metal is glass..."
  
  Not true of the 6sh7 I just destroyed.
  
  The only glass is at the base. The rest of the envelop is just metal.

    Tre is correct, in fact not long ago someone posted a link to a You Tube video on how tubes are made and it featured metal shell tubes. No glass guys!
