  • H03K 4/14 using two tubes so coupled that the input of each one is derived from the output of the other, e.g. multivibrator
  • H03K 4/16 using a single tube with positive feedback through transformer, e.g. blocking oscillator
  • H03K 4/18 using a single tube exhibiting negative resistance between two of its electrodes, e.g. transitron, dynatron
