[ARC5] VT-158 Zahl radar tube

[Fuqua, Bill L]

  OOPS, the power output is coupled off the plate terminals.

   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.
