   I have an unused EIMAC VT-158 radar tube and the frequency meter (absorption type) used with it.
Not sure where they are just now but always wondered if there was some way to snub out its 
oscillation and use it in a triode amplifier. It would look so cool. 
   I can't figure any way to do that. It has internal resonators and the output apparently is 
coupled off the filament leads where there is an adjustable hairpin stub to set its frequency.
  I fear that it will oscillate no matter what you do.
